Oh, and it has HD video up to 1080p, though there are some setbacks. More research is suggested if you&#8217;re looking into getting this. Lens sold separately.</p></div></div><h3 id="2">Getting Close &amp; Keeping Steady</h3><p><em>Animals are inherently more sensitive to the shape and form  of an upright human being than they are to vehicles.</em>  You can attribute this to the thousands of  years we’ve spent hunting them for food.   The fear that animals have for humans is well deserved.  Many wildlife photographers use expensive and  complicated blinds to hide their presence from animals.  In the right circumstances though, you  already have a working blind—<strong>your vehicle.</strong></p><p>Some more cautious animals will flee at the sight of a  vehicle.  Kestrels, for instance, flee at  the sight of a car as much as they do a human being.  But many species feel much more comfortable  around them than they do people, especially in national parks where vehicles  are a common sight, such as Rocky Mountain National Park  or Yellowstone.   I can’t tell you how many times I’ve been  able to get remarkably close to elk in <a
href="http://www.nps.gov/romo/planyourvisit/index.htm" title="Rocky Mountain National Park">Rocky Mountain   National Park</a>. </p><p>Unfortunately too often, a tourist with a  point-and-shoot camera comes along and steps out of their vehicle and  approaches the animals.  The elk shy away  or bolt into the trees, and my shoot is over.</p><p>Stabilizing your camera inside a car isn’t often easy.  You can set up some tripods so that you can  shoot from the driver or passenger seat, but some wildlife photographers find  the tripod too constrictive, especially when photographing animals on the  move.</p><div
class="image-container extra-large"> <img
src="http://tutorial9.s3.amazonaws.com/uploads/2009/03/photography-stances.png" width="600" height="300" /></div><p>In those situations, your window is your friend.  Roll up your window to the level at which you  want to set your lens.  Buy some cheap  pipe insulation with a slit down one side at any hardware store. Slip this over  the edge of the glass of your window and you can comfortably rest your lens on  the edge.   I have seen photographers use  bean bags for the same purpose. </p><p>Remember the rule of thumb to eliminate camera shake:  you should be shooting at a shutter speed at or above the effective focal length of your  lens.  That means if you shoot like I do  with a 70-300mm lens on an Olympus body with a  2x sensor <a
href="http://www.tutorial9.net/photography/crop-factor/" title="Crop Factor"><strong>crop factor</strong></a>, you need a shutter speed of at least 1/600th  of a second to help ensure that your image will be as sharp as it can be. </p><p>Tripods and the window edge trick can help  lower this shutter speed, as well as cameras or lenses with image  stabilization.  The kind of blur we’re  talking about isn’t always obvious when you check an image with your LCD.  With this rule of thumb, you help reduce the  chances of being disappointed with what you thought were great shots in the  field, but turned out to be blurry or soft when loaded onto your computer. Don&#8217;t be afraid to increase your ISO to get the shutter speeds you need. When shooting fast-moving animals such as birds in flight, you may want a shutter speed as high as 1/1000th of a second to freeze your subject. And of course, <a
href="http://www.tutorial9.net/photography/standing-steady-proven-ways-to-reduce-shake-in-photography/" title="Standing Steady: Proven Ways to Reduce Shake in Photography">proper technique in stabilizing your camera</a> can go a long way.</p><p>Most photographer recommend that you use at least a 300mm (35mm equivalent) telephoto for wildlife photography (if you need to learn more about different kinds of lenses, <a
href="http://www.tutorial9.net/photoshop/interface/lenses-and-focal-length/" title="Lenses and Focal Length Photography Tutorial">this article can help</a>) . Any less and you will have  difficulty filling the frame with your subject. But no matter how much reach your longest lens gives you, you&#8217;ll always be left wanting more. <strong>Teleconverters</strong> can be used, at the cost of sharpness and f-stops, but for bird photography involving small subjects, they may be your best option.</p><div

My area of Colorado  is rife with red-winged blackbirds in the spring.   They can be found around nearly any body of water, and the males are  claiming and protecting territory from nearly every tree branch or  cattail.  Their focus on competitors and  attracting a mate means that their guard is down more than it would be at other  times, and the cattails they often frequent are conveniently located at eye  level. </p><p>I have found that red-winged  blackbirds are an excellent “practice subject” to work on my skills of  approach, framing, and general technical work (exposure, focus, and the general  fiddling of knobs and buttons).  They are  common enough that if you blow an approach by moving too quickly or loudly,  another will most likely present itself shortly.  But they are not so easy to catch.  Dark subjects against light backgrounds can  be a technical challenge, and learning to expose the blacks of their feathers  along with that red patch can really hone your skills.</p><p>Blackbirds may not be common in your area, but most likely,  some form of wildlife frequents the parks and fields in your area.  Find a good “practice subject” and work on  your basics, so that when you go after bigger, more impressive animals, you  will have a solid foundation in the basic techniques and you will stand a  better chance of capturing a great image.</p><div
class="image-container extra-large"><img
src="http://tutorial9.s3.amazonaws.com/uploads/2009/03/practice-example.jpg" width="600" height="300" alt="Red-winged blackbirds are a good subject with which to practice." /></div><h3 id="4">Know Your Subject</h3><p><strong>Get to know your subject’s behavior. </strong> Read books and talk with hunters or experts  on the species.  Your local university  may have researchers who special in the animal you’re trying to capture.  Politely ask them for tips via email—often  they will be more than happy to share their expertise, provided you’re  respectful of the animals. </p><p>Some knowledge you will only gain through experience.  I’ve spent most of the winter travelling to Rocky Mountain   National Park on a weekly  basis.  Of particular interest in this  park are the herds of wild elk.  A large  bachelor herd is my favorite subject, but finding them in time for the good  light was not easy at first. Over time, and through trial and error, I began to  understand how weather affected which altitudes the animals could be found  at.  Colder weather or snow would push  them down into lower elevations where it they were easier to find and  photograph.  Also, I learned which park  entrances they were most likely to be near at the time of  day I was photographing them.  Other photographers in your area may be able  to share this information, but I think if you can spare the time, it’s more  fulfilling to learn their behavior on your own.</p><p>Speaking of parks, the local rangers and park staff are an  excellent resource for learning the activities and whereabouts of great  subjects.  I often swing into the pay  station later in the morning to chat with the rangers about how things have  been inside the park.  As amateur  photographers, we’re not able to spend all of our time out there, but the  rangers do, and they excellent resources at your disposal.</p><div
class="image-container extra-large"><img
src="http://tutorial9.s3.amazonaws.com/uploads/2009/03/know-your-subject-example.jpg" width="600" height="300" alt="Learning the movements of the elk allowed me to capture this shot of sparring." /></div><h3 id="5">Capture Action!</h3><p>Starting out, I was content to capture any animal in focus,  properly exposed, and decently composed.   I didn’t care so much what they were doing in the image, so long as I  got them in the shot and they weren’t just a speck in the distance.  As you develop your other skills, however,  you will find that the most compelling and successful images are one that  capture an animal in action.  It’s common  sense, but often, we forget in the excitement of just being near the animal  that that closeness is not easily conveyed through still photography. </p><p><strong>Capturing action requires more patience than just  getting the animals in the frame</strong>.  It’s  nearly impossible to approach an animal without impacting its behavior  somewhat.  They will often be rattled or  cautious in your presence.  It takes time  for the animal to settle back into its routine, to forget that you’re watching. </p><p>Increase your chances of capturing hunting or feeding  behavior by photographing at dawn and dusk.   The <strong>golden hour</strong> is great not just for light but for locating  wildlife as well.  Many animals are nocturnal or  at the least crepuscular, so they are on the move at these times.  Being out half an hour before sunrise or an  hour before sunset will help ensure that you find your subjects when they’re  doing something more interesting than chewing their cud.</p><p><strong>One last tip</strong> for capturing action with birds of prey was recently  shared with me by wildlife photographer <a
href="http://www.vicschendel.com/" title="Nature Photography by Colorado Photographer Vic Schendel">Vic Schendel</a>.   In his years of wildlife photography, he’s  discovered that raptors often defecate shortly before taking flight.  When you have the bird in your frame, and you  see this happen, starting firing off shots, because you are likely to catch a  much more impressive image of the bird taking flight than if you had taken a  shot while it rested on a tree branch or telephone wire.</p><div

In this article, we&#8217;ll go over such rights, as well as Model Releases.<span
id="more-1015"></span></p><div
class="note spacer">First a quick note, your rights and the laws surrounding photography <strong>vary from country to country</strong> and even from state to state, so always make sure what laws are in force in your area.</div><h3>Where and What can I photograph?</h3><p><img
class="alignright size-full wp-image-1017" src="http://tutorial9.s3.amazonaws.com/uploads/2008/06/photographersrights.jpg" alt="Know your rights" width="333" height="500" /><strong>The general rule</strong> is that you can photograph mostly anything you like as long as it&#8217;s in a <strong>public place</strong>. You do not need to have permission to photograph in public, this include photographing building and parks as well as people that are in public areas.</p><p>If you&#8217;re on public property you can even photograph private property, for example standing on the street and photographing someone&#8217;s garden. If you are on private property you can photograph until someone ask you to stop (a sign prohibiting photography counts as well) and you must obey such a request.</p><p>There are <strong>exceptions to this rule</strong>, for example military installations or other subjects that can be classed as national security. However infrastructures such as bridges are not included in such a list. Another exception is, even in a public space, places like dressing rooms, restrooms or people entering their code at the ATM machine — photographing at these places counts as invading a person&#8217;s privacy.</p><p>So to summarize, here are some examples of things you can photograph, if you&#8217;re in a public space you can photograph adults, children, law enforcement officers, accidents, criminal activities, celebrities, airports and train stations.</p><h3>What to do when people question you</h3><p>There is a good chance that somewhere along the way in your photography experience, someone is going to confront you. Everything from regular citizens to security personal and law enforcement officers might question your activity and ask you to stop photographing. They might say it&#8217;s for security reason and refer to acts like terrorism, <strong>this is not a valid reason for them to ask you to stop</strong> what you are doing. <strong>As long as you&#8217;re in a public space you have the right to photograph.</strong></p><p><strong>First of all, act politely and stay as calm as possible.</strong> You do not need to explain why you are there or what you are photographing. In most cases you do not need to disclose your identity (depending on your country/state you might need to do so if it&#8217;s a law enforcement officer that is requesting).</p><p><strong>You do not need to give them your camera/memory card nor do you need to delete the images.</strong> Unless they have a court order or are arresting you (again, depending on your location) they have no right to take your equipment.</p><p>If you are asked to delete photographs or asked to hand over your equipment ask for their identity and who they work for. Also ask what legal reason they cite for doing this to you. If this happens to you, you might want to consider taking legal action or contact your local newspaper.</p><h3>How and Where can I use/publish my photographs?</h3><p>Okay, so you have the right to photograph mostly anything, but are you allowed to do whatever you want with the photographs you took? The short answer is: No, there are rules and laws surrounding how you publish and distribute your photographs.</p><p>Once again, I cannot stress this enough, the laws are not the same all around the world so make sure you know what the laws says in your area before you do something you will later regret. A wrong decision can end up costing you a lot of money, not to mention your reputation as a respectable photographer.</p><p>In most areas <strong>the main difference in your rights is depending on if the photograph is used commercially or not.</strong> If your photograph is not commercial, i.e. considered art, you have much more rights to publish and use your photograph. For example, in most countries you are allowed to publish and sell photographs that are considered art without a legal release from the model/person in the photo. This means that you can go around the city photographing people in everyday situations and sell the prints or have a show at a gallery without notifying the people you photograph.</p><p>However if you intend to use the photograph in any commercial situation you will need a model release from the model. An important note is that if you sell the photograph to a commercial agency they are responsible for getting the model release from both the model and you as the photographer. If they publish your photograph without a model release you are not to blame — however all serious agencies requires a model release for every photograph they buy.</p><p>There is one gray spot though, photographers <strong>portfolios</strong>. They are used to display your work, just like commercials, but in most countries they are considered art and you do not need a model release to publish a photo on your portfolio.</p><p><strong>News photographs</strong>, even though they can be used to sell newspapers, do not require a model release to be published and sold.</p><p>As you can see this is a rather <strong>complex issue</strong>, and I haven&#8217;t even talked about how different it is from country to country, so it&#8217;s important that you check this yourself before doing a job.</p><h3>Model release</h3><p>I&#8217;ve talked quite a lot about model release, which is a form of a <strong>legal document</strong> that basically states that you as a photographer holds the rights to the photograph and can do what you want with it. These legal releases can be made very simple or they can be quite detailed; in most cases a simple one will do just fine. Before doing a large-scale job, contacting a lawyer will be well worth the money to avoid any legal problems later on.</p><p>I have designed two different samples of model releases, which could be used as a guide to what you might need/want. <strong>These samples are not intended for actual use, they are supplied as guides and should be used as such.</strong></p><p>The first one is a standard model release to be used when photographing a model for commercial use. It gives the photographer complete rights to the photographs.</p><p><a

Time-For-Print is the idea that the model gives you his/her time and for that they receive an agreed upon amount of prints for compensation. This is common for models starting out and wanting to build up a portfolio and for photographers doing the same thing. This model release is more flexible and gives options on what compensation the model is expected to receive.</p><p><a

They are signing away their rights to the photograph of themselves or their children; it&#8217;s understandably that they might have some questions or concerns so you should be thorough.</p><div
class="note"><strong>DISCLAIMER</strong></p><p>I am not a lawyer and this text should not be seen as legal advice. If you need legal advice contact a local lawyer whom have knowledge in this field.</p><p>Laws are different from country to country and even state-to-state, so contact a lawyer or local law enforcement office for specific laws in your area. Another good advice is to contact a local newspaper, they often have good knowledge what photography related laws are in place in the area they work in.</p></div> ]]></content:encoded> <wfw:commentRss>http://www.tutorial9.net/photography/your-rights-as-a-photographer/feed/</wfw:commentRss> <slash:comments>87</slash:comments> </item> <item><title>Photography Troubleshooting: No More Bad Photos</title><link>http://www.tutorial9.net/photography/troubleshooting/</link> <comments>http://www.tutorial9.net/photography/troubleshooting/#comments</comments> <pubDate>Wed, 03 Sep 2008 15:00:18 +0000</pubDate> <dc:creator>Fredrik Silverglimth</dc:creator> <category><![CDATA[Photography Basics]]></category> <category><![CDATA[Photography Tutorials]]></category><guid

If you are using auto focus and still get blurred photos it might be because the camera used another focusing point rather than the one thought you intended to use. Another reason might be the setting of the focus and then moving the camera without refocusing.</p><div

class="alignleft size-full wp-image-568" src="http://tutorial9.s3.amazonaws.com/uploads/2008/04/trouble_shake.jpg" alt="" width="150" height="150" />Camera shake is a result of unsteady hands or a too long of a exposure. To counter this you can change the shutter speed, or make the exposure time shorter. If you don&#8217;t want to change the aperture you can always change the ISO setting. Higher ISO will create noise, but noise is better than a blurry image caused by too long of a exposure time. <strong>Another option is to use a tripod or monopod.</strong></p><p>For more information about this topic, you may like to read our tutorial on <a

class="alignleft size-full wp-image-569" src="http://tutorial9.s3.amazonaws.com/uploads/2008/04/trouble_motion.jpg" alt="" width="150" height="150" />This is the result of photographing a moving object with a too long exposure… <em>no matter how steady you are</em>. A faster shutter speed is the only solution in this problem — <strong>some action sports require speeds as quick as 1/1000+.</strong></p><div
class="clear spacer3"></div><h3>Too Much Contrast</h3><p><img
class="alignleft size-full wp-image-570" src="http://tutorial9.s3.amazonaws.com/uploads/2008/04/trouble_hcontrast.jpg" alt="" width="150" height="150" />The sensor is not able to pick up the whole spectrum of light and expose it correctly in some situations. Unless you want to manipulate your photographs in post-production (such as HDR) you have two options: either select the part of the scene that is most important to expose correctly, or use a graduated ND filter to get the entire scene exposed correctly (<em>primarily used in landscape photography</em>).</p><div
class="clear spacer3"></div><h3>Add More Contrast</h3><p><img
class="alignleft size-full wp-image-571" src="http://tutorial9.s3.amazonaws.com/uploads/2008/04/trouble_lcontrast.jpg" alt="" width="150" height="150" />Low contrast can be a result from photographing in bad lighting conditions, or in unique instances, environments can play a role in this problem <em>(such as a snowy landscape)</em>. This is most often easily fixed in Photoshop by using the adjustment layer Levels to change the black and white point. The example photograph is lacking contrast due to stray light reaching the sensor, which can be countered by using a lens hood.</p><p>Here&#8217;s a good article that shows how to <a

class="alignleft size-full wp-image-572" src="http://tutorial9.s3.amazonaws.com/uploads/2008/04/trouble_flare.jpg" alt="" width="150" height="150" />A lens flare is created when the lens picks up stray light. The best way to block out this unwanted light is to use a lens hood. Different lenses create different lens flares — cheaper lenses usually create uglier flares than high-end lenses, but even with a high-end lens one should always use a hood to minimize the risk.</p><div
class="clear spacer3"></div><h3>Prevent Double Lights</h3><p><img
class="alignleft size-full wp-image-573" src="http://tutorial9.s3.amazonaws.com/uploads/2008/04/trouble_doublelight.jpg" alt="" width="150" height="150" />This is an optical effect that can occur in low light situations in combination with some (often cheaper) lenses. <strong>A UV filter can increase this effect, so if you notice these types of odd lights on your night photographs you might want to consider removing the UV filter for the duration of the shoot.</strong></p><div
class="clear spacer3"></div><h3>Underexposure</h3><p><img
class="alignleft size-full wp-image-574" src="http://tutorial9.s3.amazonaws.com/uploads/2008/04/trouble_underex.jpg" alt="" width="150" height="150" />Not enough light reached the sensor, you need to change the exposure settings to get a correctly exposed photograph. Either a slower shutter speed, a larger aperture or higher ISO — or all of them combined.</p><p>Read more about <a

class="alignleft size-full wp-image-575" src="http://tutorial9.s3.amazonaws.com/uploads/2008/04/trouble_overex.jpg" alt="" width="150" height="150" />Too much light reached the sensor — you need to change the exposure settings to get a correctly exposed photograph.

class="alignleft size-full wp-image-576" src="http://tutorial9.s3.amazonaws.com/uploads/2008/04/trouble_vignette.jpg" alt="" width="150" height="150" />Vignette are dark corners in a photograph, which occur when the light is not evenly distributed on the sensor or when the flash just lights up the center of a shot.</p><p>Many lenses, even high-end, create this effect when opened wide (largest aperture). <strong>To fix this problem simply stop down the aperture a few stops and this should even out the distribution.</strong></p><div
class="clear spacer3"></div><h3>Lens distortion</h3><p><img
class="alignleft size-full wp-image-577" src="http://tutorial9.s3.amazonaws.com/uploads/2008/04/trouble_distortion.jpg" alt="" width="150" height="150" />Mostly a problem when photographing architecture with a wide-angle lens. A lens below 50mm usually creates some distortion but in most cases this is not visible. However when you are photographing straight lines (such as buildings), standing close to the object and pointing the camera upwards you will more easily see these distortions. Take a few steps backward or change to a more suitable lens.</p><p>For more information, read our article about different <a

class="clear spacer3"></div><h3>Skewed horizon</h3><p><img
class="alignleft size-full wp-image-578" src="http://tutorial9.s3.amazonaws.com/uploads/2008/04/trouble_skewed.jpg" alt="" width="150" height="150" />You were either holding the camera skewed or the tripod was set up uneven. Some DSLR cameras have the ability to change the focusing screen and install one that has guidelines. This is rather easily fixed in post-production by rotating the image, but you will loose some of the edges.</p><div
class="clear spacer3"></div><h3>Red eyes</h3><p>This effect occurs when the flash is located close to the lens and is a common problem with our modern point-and-shoot-cameras due to their placement of the flash. To prevent red eyes, do not use the cameras internal flash if your camera has one. Use an external flash that you can bounce on a wall or on the ceiling.</p><div
class="clear spacer3"></div><h3>Reduce Noise in Photographs</h3><p><img
class="alignleft size-full wp-image-584" src="http://tutorial9.s3.amazonaws.com/uploads/2008/04/trouble_noise.jpg" alt="" width="150" height="150" />Most likely due to a high ISO setting, but can also be caused by long exposures. To prevent noise, use a low ISO setting. If you have photographs with much noise you can always use a software to remove it, such as Photoshop or Noise Ninja, though some detail will be lost of course.</p><p>You can learn more about ISO, Aperture, and other essential subjects in our <a
href="http://www.tutorial9.net/photography/photography-basics/">Photography Basics</a> article.</p><div
class="clear spacer3"></div><h3>Photo is yellow/orange tinted</h3><p><img
class="alignleft size-full wp-image-583" src="http://tutorial9.s3.amazonaws.com/uploads/2008/04/trouble_tinty.jpg" alt="" width="150" height="150" />The camera is most likely to have miscalculated and thought the photograph was outdoors and added orange tones to compensate. The white balance is the fault here, and if you&#8217;re <a
href="http://www.tutorial9.net/photography/the-power-of-raw-photography/">photographing in RAW</a> there&#8217;s no problem since you can easily just change the white balance to a desired level. If you&#8217;re not using RAW-files then you might want to check your settings in the camera — <em>most cameras have W/B setting for indoors and outdoors, as well as custom settings and auto</em>. The fault could also be that you used a flash that bounced off an orange surface as well, so try to always bounce the flash at a neutral surface, such as gray.</p><div
class="clear spacer3"></div><h3>Photo is blue tinted</h3><p><img
class="alignleft size-full wp-image-579" src="http://tutorial9.s3.amazonaws.com/uploads/2008/04/trouble_tintb.jpg" alt="" width="150" height="150" />These photographs look very cold and are most likely due to a miscalculation by the camera and just like the previous problem discussed, you can fix it the same way. Another reason why a photograph can get a blue tint is because of large amounts of UV-light, to reduce this problem use a UV-filter that prevents the UV-light to reach the sensor without affecting the overall quality of the photograph. (Not a problem for most digital SLR cameras.)</p><div
class="clear spacer3"></div><h3>Photo is half black</h3><p><img
class="alignleft size-full wp-image-580" src="http://tutorial9.s3.amazonaws.com/uploads/2008/04/trouble_flashsync.jpg" alt="" width="150" height="150" />The flash doesn&#8217;t sync correctly with the camera (shutter). This problem was more predominant before the digital era, but old flashes can still cause problems with newer technology. Either buy a new flash or learn which shutter speeds work best — 1/125 and 1/60 are usually good.</p><div
class="clear spacer3"></div><h3>Chromatic aberration</h3><p><img
class="alignleft size-full wp-image-581" src="http://tutorial9.s3.amazonaws.com/uploads/2008/04/trouble_ca.jpg" alt="" width="150" height="150" />Chromatic Aberration (sometimes also called &#8220;purple fringing&#8221;) is an optical effect and it&#8217;s seen as purple edges around an object, sometimes green edges on the opposite side are also visible. This effect is most common in situations with strong contrast, such as sunlight against dark objects or black text on white background. The problem is more prominent on zoom lenses, the longer the range the worse the problem usually is. To prevent it you could use a smaller aperture — <em>shooting with the lens wide open will enhance the problem</em>.</p><div
class="clear spacer3"></div><h3>Sensor Dust</h3><p><img
class="alignleft size-full wp-image-582" src="http://tutorial9.s3.amazonaws.com/uploads/2008/04/trouble_dust.jpg" alt="" width="150" height="150" />These gray spots are usually caused by sensor dust. The best way to get rid of this problem is to keep your gear clean and dust free. The sensor is very sensitive and cleaning it will mean that you expose it to further risks. Some photographers send their cameras to be cleaned while others clean the sensor themselves. Choose which option you like best.</p><div

What does it mean that a camera has a crop factor of 1.6x and how does it affect your focal length? We try to untangle this issue and describe it as clearly as possible.<span
id="more-876"></span></p><p>The subject of crop factors and focal length multiplier can be a bit confusing and hard to understand at first — I will try to explain it as simple as possible but yet informative enough for you to get the entire picture.</p><p><strong>The size of the sensor</strong> is what controls the crop factor, and it&#8217;s always compared to a <strong>35mm film</strong> size. So when people talk about <strong>Full Frame</strong> they are talking about cameras that have a sensor the same size as a 35mm film (24&#215;36mm).</p><p><img
class="aligncenter size-full wp-image-878" src="http://tutorial9.s3.amazonaws.com/uploads/2008/05/crop-factor-photo.jpg" alt="" width="590" height="590" /></p><p>As you can see in the illustration above, a body with a <strong>crop factor captures only the center part of the image</strong>. The image itself is round because that&#8217;s what the lens produces, and the sensor only picks up the light that reaches it. A full frame sensor will capture edge to edge of what the lens capture.</p><p>It&#8217;s important to know that the crop factor changes the field of view, it doesn&#8217;t actually change the focal length, since that is something that is decided by the design of the lens. The same results could be produced by taking a photograph with a full frame camera and crop it to only show the center — however it would require a camera with a good enough sensor that such a small crop would still produce a good quality image. These high-end sensors are currently only found in the top of the line cameras from Nikon and Canon.</p><p>What it also means is that <strong>the perspective doesn&#8217;t change with the crop factor</strong>, if you stand on the same spot and take a photograph with a full frame camera with a 50mm lens and then take another photograph with a 1.6x crop factor camera you will get the exact same perspective (the 1.6x camera will however not have the same view of field).</p><p>When people say that a <strong>50mm lens</strong> is the natural focal length they talk about perspective in relations with the human eye, and as stated above, this is the same even on cropped bodies, a 50mm lens still produces a natural looking photograph. To test this, use a 50mm lens and look through the viewfinder with one eye and have your other eye open, you will notice that the perspective looks the same for both eyes, no matter if you&#8217;re using a cropped body or not.</p><h3>Lenses designed for Crop Factor cameras</h3><p></p><p>To counter this issue, most lens manufacturers have designed some lenses that are only meant to be used on cameras with a crop factor (i.e. not on full frame bodies). These lenses often <strong>produces a smaller image circle</strong> so if they were used on full frame bodies they would create a black edge, much like circular fish eye lenses do. Since the problem with crop factor is mainly negative with wide-angle lenses it&#8217;s almost entirely that focal range that has designated digital lenses.</p><p>Here is a list of the name camera manufacturers call their digital only lenses.</p><ul><li><strong>Canon</strong> — EF-S</li><li><strong>Nikon</strong> — DX</li><li><strong>Sony</strong> — DT</li><li><strong>Pentax</strong> — DA</li><li><strong>Sigma</strong> — DC</li><li><strong>Tamron</strong> — Di-II</li></ul><p>One thing to remember is that the crop factor is still in use even on these cameras and you must multiply the given focal length to get the &#8220;correct&#8221; focal length. For example, Canon has an ultra wide EF-S lens that has a focal length of 10-22mm, on a body with a 1.6x crop factor the focal length corresponds to a 16-35mm.  So don&#8217;t believe that you do not need to multiply the focal length just because you have a lens designed from cropped bodies.</p><h3>How it affects your photographs</h3><p>There are both positive and negative affects with the crop factor, let&#8217;s talk about the <strong>positive aspects first</strong>.<br
/> To get the &#8220;correct&#8221; focal length you need to <strong>multiply</strong> the focal length with the crop factor. When I say correct I mean the focal length that the lens acts like, not what it truly is. My camera has a crop factor of 1.6x and that means that a 50mm lens is a 80mm lens (50&#215;1.6=80). It also means that a 100-400mm lens is actually a 160-640mm lens. That&#8217;s a very good thing in most situations. You loose 60mm on the short end but gain 240mm on the long end — rather significant. With telephoto lenses the crop factor is often desirable, since it extends your &#8220;reach&#8221; quite a bit.</p><p>Another positive affect is that almost <strong>all lenses are much sharper in the middle</strong> and softer on the edges. How can this be a good thing? Well with a camera that has a crop factor you only get the center of what the lens sees (unless it&#8217;s a lens designed for crop factors as described above). So with a crop factor you only get the center and therefore the <strong>best performance from your lens</strong>.</p><p>Now over to the <strong>not so good aspects</strong> of the crop factor. <strong>Wide-angle lenses</strong>, this is a big minus on the bodies with smaller sensors. As the example above, the 10-22mm ultra wide turns into a 16-35mm lens, and for example a 17-40mm lens turns into a 27-64mm lens. You simply do not get the same wide angles with a crop factor, <strong>the edges are cut off and field of view is more limited</strong>.</p><p>Another negative affect is that the extra focal length you gain also means that you increase the risk for blur due to camera shake. The rule that you should have a shutter speed of 1/focal length is no longer true. For this rule to be true you first need to multiply your focal length with the crop factor of the body.</p><p>Full frame camera often have a <strong>larger viewfinder</strong> as well. When I&#8217;m comparing my old 35mm film camera with my 1.6x crop DSLR it actually makes me a little bit sad inside. The viewfinder on the 35mm camera is so large and bright where as the DSLR&#8217;s viewfinder is although bright still very very small.</p><p>There is one more thing a smaller sensor affects, but it would be hard to classify it as either good or bad. <strong>Different sizes of sensors change the depth of field.</strong> A smaller sensor will give you greater depth of field (more in focus) and a full frame sensor will give you a narrower depth of field (less in focus). If this is good or bad is dependent on what you desire, either you want as much as possible in focus or you want to isolate your subject as effective as possible.</p><p>I hope I didn&#8217;t confuse you too much. This is an important part of digital photography to understand, at least the very basics of it.<a

No camera bag is made to fit every occasion so I will here talk about some different types of bags and cover a few points to consider.</p><p>Choosing your next lens or camera is often quite easy, you often know what you want, but when it comes to choosing a new camera bag at least I can be confused and have a really hard time deciding. I will talk about different types of bags, and go into some more detail on a specific model in each category.</p><h3>Shoulder bag — LowePro Nova 5 AW</h3><p><img
class="alignnone size-full wp-image-727" src="http://tutorial9.s3.amazonaws.com/uploads/2008/05/camerabag_nova5.jpg" alt="" width="590" height="342" /></p><p></p><p>Shoulder bags make accessing your gear easy and quick, often a good choice for urban photographers. They come in all different shapes and sizes, many of them have the great feature of not looking like a camera bag, which is often appreciated since it attracts less attention from ill-willing citizens. I would recommend brands like Domke and Crumpler if this is what you&#8217;re looking for.</p><p>The <a
href="http://www.lowepro.com/">LowePro</a> Nova 5 AW does not fit the above description, it&#8217;s a rather large bag and bulky. I personally dislike shoulder bags because I&#8217;m not an urban photographer. When I take a bag with me it&#8217;s often because I go on long hikes for several hours and shoulder bags tend to be tiresome and not the best solution for my style of shooting.</p><p>I use the Nova 5 as a storage bag and it&#8217;s a bag that I take with me when I&#8217;m going to be shooting on one location and not move around a lot. As you can see it can swallow quite a large amount of gear, in the picture above I have 6 lenses (1 large, 3 medium and 2 small lenses) as well as my Canon EOS 350D with attached grip. Also stored in the main compartment are a set of extension tubes and several filters, in the front compartment I have memory cards, spare batteries, an air blower and other assorted stuff.</p><h3>Quick access backpack — LowePro Slingshot 200 AW</h3><p><img
class="alignnone size-full wp-image-728" src="http://tutorial9.s3.amazonaws.com/uploads/2008/05/camerabag_slingshot200.jpg" alt="" width="590" height="396" /></p><p>If you&#8217;re looking for a backpack with quick access, look no further, the LowePro Slingshot 200 AW is perfect for most situations. It&#8217;s small enough to not be in your way, and the &#8220;sling-feature&#8221; makes accessing your gear easy. How it works is that the bag only has one shoulder strap and you can flip it from your back to your waist with a single pull. LowePro also has a series of backpacks that have the same features but uses two shoulder straps called Fastback (the design is obviously a bit different but the idea is the same).</p><p>The Slingshot comes in different sizes, the 200 being the medium model and it is surprisingly roomy inside. It&#8217;s easy to rearrange the dividers and design your own interior, I have it arranged so that I can access all my gear fast and don&#8217;t need to open the zipper all the way. In the main compartment in the picture above I have 4 lenses (1 large, 1 medium attached to the camera and 2 small lenses), my 350D with grip and a set of extension tubes and memory cards. In the small front compartment I have spare batteries and some filters. In the top compartment I have a pocket book, a notebook, a flashlight and an air blower.</p><p>If you rearrange the dividers I&#8217;m sure you could be able to fit in 1 or 2 more lenses, but access might not be as easy that way — it&#8217;s all up to you to form your camera bag the way you want it. The bag also make use of LowePro&#8217;s Slip Lock system which means that you can attach extra lens cases on the outside of the bag.</p><p>I highly recommend this backpack.</p><h3>Backpack — Kata R-103</h3><p><img
class="alignnone size-full wp-image-729" src="http://tutorial9.s3.amazonaws.com/uploads/2008/05/camerabag_r103.jpg" alt="" width="590" height="500" /></p><p>A true backpack is a great choice if you go on long hikes or travel between photo sessions, as well as longer travels such as with airplanes. It&#8217;s not as accessible and quick as the other options above, but it&#8217;s far more comfortable and your gear is more safe with most backpacks (they often have better and more padding) and most backpacks have room for more equipment as well.</p><p>The company <a
href="http://www.kata-bags.com/">Kata</a> that among other things make military armor also makes this backpack, the Kata R-103. This is a company that knows a thing or two about protection and how to keep your camera gear safe. And I must say, I trust that my camera gear is safe when it&#8217;s in this bag, the design is sturdy as a tank but still rather lightweight.</p><p><img
class="alignleft size-full wp-image-730" src="http://tutorial9.s3.amazonaws.com/uploads/2008/05/camerabag_r103_2.jpg" alt="" width="213" height="351" /></p><p>This is the most comfortable backpack I&#8217;ve ever used, non-photo related backpacks included. I have walked for hours with this bag and attached tripod on my back (total weight 24lbs/11kg) without actually feeling that I was carrying something. The design of the bag is amazing to say the least, you have a quick access zipper to be able to pick up the camera without opening the whole main compartment. Using this zipper you will also be able to access the storage pocket that is in the lid, this is where I keep my memory cards and spare batteries.</p><p>The main compartment is not as deep as many other backpacks, which means that most lenses will have to lay down in this bag, only smaller lenses will be able to stand up so to speak. This results in a bit smaller main compartment than most other backpacks, so this bag might not be the best choice if you have several larger lenses. In the picture above I have 5 lenses (1 large, 2 medium and 2 small), my 350D with grip as well as some filters. That is the content of my main compartment, in the lid I keep my batteries, memory cards, rain cover, remote control as well as some other assorted stuff. There are two smaller pockets on the front of the camera where I keep an air blower, extra quick release plate for my tripod as well as a flashlight and lens tissues.</p><p>On the backside of this bag there&#8217;s also a compartment for a laptop, up to 15&#8243;. This is a great feature that makes it easy to take your photo lab out on the field. When I&#8217;m not storing a laptop in this compartment I use it for documents or an extra sweater.</p><p>So all in all I think you will find that most, if not all, of your equipment will fit in this bag. And as I said earlier, it comes with a tripod mount to be attached on either the front or one of the sides. The R-103 uses Kata&#8217;s EPH system, which means that you can combine several Kata products and attach to each other to maximize your customizability and space. This bag is stated to be within the carry-on restrictions for airplanes, but if you plan on traveling with this bag, make sure about the size restrictions on your airport since they can vary quite a bit.</p><p>I highly recommend this backpack, it&#8217;s one of the best photo related purchases I&#8217;ve ever made.</p><h3>Lens Case — Canon LZ1324</h3><p><img
class="alignnone size-full wp-image-731" src="http://tutorial9.s3.amazonaws.com/uploads/2008/05/camerabag_lenscase.jpg" alt="" width="493" height="322" /></p><p>Lens cases are designed to carry just one lens, and they are a great option if you want to take an extra lens with you when you&#8217;re shooting. Another great usage for these cases are when they are attached to either a camera bag or a harness of some sort (more on this later). Lens cases are also a great way to keep your lenses safe during travels, but be sure to use a case that fits your lens. There are so many different sizes and it&#8217;s important to get the best possible fit to avoid having a lens that rattles around in there.</p><h3>Camera Vest &amp; Harness</h3><p>A vest is a well-used alternative to a bag, it keeps all your equipment within arms reach. With its large and many pockets you can often fit the same amount of gear that you would in a small to medium backpack. Another alternative is the harness or belt on which you can attach several lens cases or smaller bags. This gives you more customizability than a vest and also keeps your equipment more protected, but a harness is often bulkier and more expensive.</p><p>Vests can be found in most photo stores (don&#8217;t know any good brand) and harnesses you should look into are <a
href="http://www.lowepro.com/">LowePro&#8217;s</a> and <a
href="http://www.thinktankphoto.com/">Think Tank&#8217;s</a>.</p><h3>Weather cover</h3><p><img
class="alignnone size-full wp-image-732" src="http://tutorial9.s3.amazonaws.com/uploads/2008/05/camerabag_weathercover.jpg" alt="" width="590" height="371" /></p><p>For me weather cover is essential, as you can see in the picture above, all my camera bags comes with weather cover (lens case excluded). The two LowePro bags have their rain covers sewed into a compartment in the bag and can&#8217;t be removed. The Kata bag has a loose rain cover that can be taken off and left home if you like too, it even comes with an alternative silver side for reflecting sun, this side can also double as a light reflector which is a nice touch.</p><p>I would never buy a camera bag that didn&#8217;t have rain cover, but then again I live in a country where rain can come any day, anytime of the year. If I&#8217;m out hiking or taking a bike ride I don&#8217;t want to find myself hours from my home/car and nowhere to find cover, but if you&#8217;re not in these situations it might not be such an important factor for you. Choosing a camera bag is all about your needs, your equipment and photographing style.</p><h3>Carrying a tripod</h3><p>A tripod can be a real pain to carry with you, and this is the most common reason why so many photographers leave their tripods at home where they do no good. There are several good tripod cases and bags, but I myself find these a bit bulky or unnecessary. I do one of two things, either attach a shoulder strap to the tripod and carry it without a case or attach it to my backpack. Just remember, a tripod will not help you improve your photos if it&#8217;s left at home, so find the best solution for you to be able to have it with you every single time you might need it.<a

isPermaLink="false">http://www.tutorial9.net/?p=585</guid> <description>&lt;img src="http://www.tutorial9.net/" alt="" width="600" height="260"/&gt;</description> <content:encoded><![CDATA[<p></p><p>Photography is all about preparation.  Instead of running into problems when you&#8217;re out shooting, understand some easy ways of tackling the more common problems you may run into!</p><p></p><h3>Batteries</h3><p><img
class="alignleft size-full wp-image-587" src="http://tutorial9.s3.amazonaws.com/uploads/2008/04/batteries.jpg" alt="batteries Photography: Little Known Ways to Avoiding Problems" width="150" height="101" title="batteries image" />Always, and I mean <em>Always</em>, keep and an extra battery in your camera bag at all times. You will need to change battery in the field sometimes and it&#8217;s important to be well prepared. It&#8217;s important to know that <strong>if you&#8217;re photographing in low temperatures your camera will drain the battery faster</strong> so always stack up on some extra batteries when your out in the cold.</p><p><strong>Don&#8217;t buy cheap batteries</strong>, it will only come back to haunt you in the end. In most cases it&#8217;s best to buy the &#8220;official&#8221; battery for the camera. For instance I have both Canon and non-brand batteries for my Canon EOS 350D; my Canon batteries will last for approximately 5000 photographs (using a vertical grip with 2 batteries) while the non-brand batteries will last somewhere around 200-400 photographs (under the same conditions). This is a huge difference, and I can only say that I&#8217;ve learned from my mistake.</p><p>Unless you really need it, turn off the LCD. <strong>The LCD drains the battery</strong> like nothing else, just <strong>lowering the brightness</strong> of the display will add some extra hundred photographs per charge. The auto display feature should be used with care, if you really need it to be on, at least lower the time the photograph is displayed to the minimal time you need.</p><h3>Changing Lenses &amp; Sensor Dust</h3><p>Changing lenses will leave the interior of your camera body exposed to the outside world. It&#8217;s important to realize that you should <strong>be very careful when changing lenses</strong>. Have your back faced towards the wind to minimize dust getting inside and try to avoid changing lenses in the most dust filled areas. If possible, <strong>only change your lens in areas that are relative dust free</strong>, such as indoors or in a car.</p><p>When you change lenses, do the following to minimize the risk of dust getting inside the camera:</p><ul><li>Have your camera hanging around your neck</li><li>Take the new lens in one hand and take off the back lens cap</li><li>Unscrew the lens that&#8217;s on the camera and quickly switch lenses</li><li>Put the back lens cap on the used lens</li></ul><p>If you get dust on the sensor, be careful — it&#8217;s very sensitive equipment. Some people choose to send their cameras in for a sensor cleaning while others clean the sensor themselves, choose which solution you think is best for you.</p><div
class="tip"> I personally clean the sensor myself. I use an air blower to clean the sensor, but it&#8217;s also perfect for cleaning your lenses and filters. I keep one in each of my camera bags.</p><p>If you&#8217;re using an air blower, don&#8217;t place the tip inside the camera body — always have the tip outside of the camera body. If the mirror would flip down the air blower might otherwise get hit and scratch the sensor.</p><p>I&#8217;ve never used anything directly on the sensor, just blown air onto it, but there are other methods — I guess I wouldn&#8217;t trust myself with most of them.</p></div><h3>Lens Hood</h3><p><img
class="alignleft size-full wp-image-588" src="http://tutorial9.s3.amazonaws.com/uploads/2008/04/lens_hoods.jpg" alt="lens_hoods Photography: Little Known Ways to Avoiding Problems" width="250" height="141" title="lens_hoods image" />Lens hoods are often overlooked, but they can improve your image quality as well as keeping your lens protected. The hoods primary job is to block unwanted light from reaching the sensor and thus prevent glare and lens flare. Lens flare can destroy otherwise fine photographs, it&#8217;s unwanted and a lens hood is the best way to prevent it — unless you always want to shoot with your back towards the light source(s).</p><p>The lens hoods can also be used for protection. With a hood on you&#8217;re less likely to accidentally touch the optics. If you&#8217;re photographing kids or animals at close range this will also help you from getting unwanted smudges on the lens, because we all know how much kids and animals love shiny things. Using a lens hood when shooting macro is a perfect way to keep your distance to the object and minimize the risk of accidentally bumping into it.</p><p>If you drop your lens the hood will most likely take most of the damage (but interior mechanics of the lens might still be damage from a fall, a hood will not protect against that) and hopefully save the lens.</p><p></p><div
class="note">There is one occasion when you should not use a hood, and that&#8217;s when you are using a flash. The lens hood can cast a shadow on the object, which is most unwanted. You can angle your flash to bounce on another neutral surface to avoid this shadow if you still want to use the hood.</p><p>You will have to test your equipment and see if your lens/flash combo will cast a shadow or not.</p></div><h3>Extra Memory</h3><p><img
class="alignleft size-full wp-image-589" src="http://tutorial9.s3.amazonaws.com/uploads/2008/04/cf_cards.jpg" alt="cf_cards Photography: Little Known Ways to Avoiding Problems" width="150" height="116" title="cf_cards image" />Just like with batteries, always take more memory than you think you&#8217;ll need. You never want to find yourself in a situation where you are unable to photograph due to the fact that your memory card is full. I would also advice against deleting any photograph directly from the camera. No matter how large or bright the LCD is, it will not show you what the photograph really looks like (sharpness and such fine detail). If a photo is a complete failure, such as just black/white, you can usually make the decision to delete it right there and then, but if you for example think that the photograph looks blurry I would strongly advice against deleting such a photograph. Better safe than sorry — so bring extra memory!</p><p>Another quick note when it comes to memory cards, if you&#8217;re in extreme environments — deserts, north of the Arctic Circle etc — you should spend the extra bucks on a SanDisk Extreme III-IV card. Not only are they faster but they are constructed to withstand more abuse and have a greater range of working temperatures. (Obviously these cards are faster even under normal circumstances, so it could be worth the money just for the speed alone depending on your set-up.) <a

This article will deal with some of the adjustments you can use to develop your photographs in the digital darkroom.<span
id="more-562"></span></p><p>The software I have used in this article is Photoshop CS3 (on a Mac) but most of these features are available in any decent photo-editing software.</p><h3>Levels</h3><p>Levels are one of the most important tools to use when you are working with post-production. This adjustment layer is used to <strong>correct or enhance the histogram</strong>. <em>To learn more about what the Histogram shows and how it works, please read my article about it.</em></p><p>A word of advice is to <strong>work with levels in a separate layer</strong> instead of working on the actual photo layer.</p><p>There are two methods to use this adjustment layer:</p><h4>SET WHITE &amp; BLACK POINT</h4><p>This method will give you an <strong>eyedropper</strong> and you will have to set one point for the darkest (<strong>black point</strong>) and one point for the lightest (<strong>white point</strong>) area. There is also the option to set the <strong>grey point</strong> (18% grey, in the middle of the tones).</p><p>This can be a bit tricky to the beginner, but it&#8217;s a very powerful tool. It&#8217;s often easy to spot the white point in the photo, often from a light source or something white and/or reflective. The black point may be a bit harder to locate, the best way is to think about where the light is the least likely to be reflected.</p><p>In the photograph below you can see that the white point is where you can spot a cloud in the sky behind the trees and the black point is inside the poor sheep&#8217;s nostril — there isn&#8217;t much light reaching in there.</p><div

class="alignnone size-full wp-image-990" title="Manually adjusting Levels in Adobe Photoshop" src="http://tutorial9.s3.amazonaws.com/uploads/2008/06/levels.gif" alt="Manually adjusting Levels in Adobe Photoshop" width="591" height="268" /></p><p
style="text-align: center;"><em>An example of a levels slider from Adobe Photoshop CS2.  Similar Level Adjustments can be found in other software, including GIMP.</em></p><p>Instead of stretching out the histogram you <strong>narrow down the field</strong> by moving the dark and the light levels in this method. You can achieve the same effect as the method listed above, but you will be able to see the gradual change in the photograph better this way. What you want to do is dragging the black triangle to the right until it&#8217;s under the left edge of the graph, and drag the white triangle until it&#8217;s under he right edge of the graph. If you have a histogram like the one above you might want to move the white triangle a little more to the left than the very edge since the levels of white are very small at the edge.</p><p>Which of the two methods you like the best is up to you, try the both out and see what you like the most. (I only go through how to use the RGB level here, there will be some more info on the other levels later in this article.)</p><h3>Curves</h3><p><img
class="alignnone size-full wp-image-991" title="Using Curves from Adobe Photoshop" src="http://tutorial9.s3.amazonaws.com/uploads/2008/06/curves.gif" alt="Using Curves from Adobe Photoshop" width="591" height="305" /></p><p>This adjustment layer is quite like the levels, but with a bit more control. You can choose to either set the black/white or you can create your own curves. Unlike the Levels layer,  Curves will often times have easy to use Presets, either the standard ones that come with the software or your own custom ones.</p><h3>Sharpening</h3><p>This is something that has to be done on a photo layer, so you might want to duplicate your photo layer (usually the <em>background layer</em>).</p><p>Go to <strong>Filter -&gt; Sharpen -&gt; Unsharp Mask</strong></p><p>The settings here are very different depending on whether you&#8217;re photographing portraits, landscapes, urban etc. But somewhere around <strong>Amount: 85, Radius: 1, Threshold: 0</strong> <em>or</em> <strong>Amount: 100, Radius: 0.5, Threshold: 0</strong>. Try and see where you find a good spot between sharp and overly sharpened — white halos will appear around some object if you sharpen the image too much, this will not look good.</p><p>There is nothing that can beat a sharp image straight out of the camera, but Unsharp Mask can at least help you get a little closer.</p><h3>Color correction</h3><p>Color correction is an important but difficult part of post-production. There are several different ways to deal with untrue colors. It depends on what the problem is; is it just one colors that is off, is the entire photo lacking color, is the photo tinted in a weird color? Each of these problems need a different tool, I will go through the very basics of some of the color correction tools that Photoshop have.</p><p><strong>Selective Color</strong> — Controls several different colors and can do just about anything to a specific color. This is a great adjustment layer to use when a specific color is untrue in the photograph, such as a green shirt looking blue.</p><p><strong>Channel Mixer</strong> — The RGB channels, can add and subtract RGB from each channel. A good tool when an entire image is experiencing a colored overcast.<br
/> <strong>Hue/Saturation</strong> — This layer have three main settings; Hue, Saturation and Lightness. Stay away from Hue and Lightness unless you know what you&#8217;re doing. Saturation is a great tool to boost or drain the colors.</p><p><strong>Color Balance</strong> — Here you have RGB again, with different settings for Shadows, Midtones and Highlights. Can be used to correct the color in just one of those areas.</p><p><strong>Levels &amp; Curves</strong> — Use it like described above, but change the channel to one of the RGB ones. You will be able to control the colors with good accuracy. Works good both with highlights/shadows as well as photos with a color overtone.</p><h3>Dodge &amp; Burn</h3><p>These two tools are designed to mimic the effect of the Dodge and Burn tools used in <strong>darkrooms before the digital age</strong>. These tools are used to change the exposure on selective parts of the photograph, such as giving more exposure to shadowed areas.<br
/> The Dodge tool will lighten up parts, the Burn tool will darken parts.</p><p>Use them with care, but when you&#8217;ve mastered them they can be a great asset to change your exposure on just some parts in post-production.</p> ]]></content:encoded> <wfw:commentRss>http://www.tutorial9.net/photography/digital-adjustments/feed/</wfw:commentRss> <slash:comments>16</slash:comments> </item> </channel> </rss>
