Digital cameras you several options to control their exposure. Know how to use them to get the best results for your photography? In the first SLR cameras (film) were totally manual. A photographer needed to understand the configuration of opening and shutter and how to use them. Then came the automatic mode, allowing the camera does the thinking for you. This was (and remains) a fairly reliable way to get a well exposed image, but he had the creativity of the photographer's hands. Over time, few people learned manual dexterity. As camera technology improved, the quality of most of the photos even worse. Today we have the best of both worlds. All DSLR cameras and compact digital cameras have automatic and manual modes, but also offer semi-automatic mode. This means that you can get a little 'creative, and allow the camera to control exposure for you. If you have the priority and aperture priority shutter of the camera, but never understood what they were, this article is for you. First, that it is openness and speed? These are the two mechanisms to control the level of exposure in the photos, if your photo will be overexposed, underexposed, or just right. To explain properly would require much more in-depth article, that's just a quick downward. The opening is the size of the hole that allows light into the picture. Think about how the iris in the eye – as the light is low, you open the aperture to allow more light inch aperture also controls the depth of field, which affects the amount of your image is in focus. When you have a small opening, has a great depth of field, so that the subject and the environment can be in focus. When the opening is wide, the depth of field is much smaller, making it much less space around the subject, which will be focused. Shutter speed is the time allowed to each show. The shutter opens to allow light, so that the most open, the brightest of the show will be. The shutter speed also controls how motion capture in a photo. If you want to freeze a moving subject, you must use a fast shutter speed. The trick is to combine the opening and adjusting the shutter speed to get better results. If you get the right balance, your photo is perfectly exposed, and you have creative control over the look of the image. Of course, this is easier said than done. To help manage the challenge, now has the option of opening and shutter priority. These semi-automatic mode let you take control of a stage, and the camera automatically adjusts the other. This allows you to have some creative input, with the safety net of knowing that the camera allows you to manage the level of exposure. You decide how you want your picture to look, and the camera make sure it is properly exposed. So, what you choose: Shutter Priority or Aperture Priority? Well, it's all a question of priorities …. Remember that the opening of controls depth of field. So, if the range of fire is the critical element in the photo, choose the priority of opening. You can set a small aperture to maximize depth of field, or a large opening to focus attention on the issue. In any case, the camera adjusts the shutter speed to give the best exposure. The shutter speed controls the movement in a photo. If control of a moving object is the cornerstone of your image, select the priority of speed. This allows you to set a fast shutter speed to freeze subject movement, or a slow shutter speed to capture motion blur. Whatever you choose shutter speed, the aperture of the camera to ensure that the picture is exposed correctly. So the choice of aperture priority or shutter-priority depends on the type of subject to photograph and how you want to display in the photo finish. It 'really a perfect marriage between art and technology, which allows you to concentrate on their creative choice and not technical problems. There is much to learn about this topic, a short article like this is just a starting point. However, if you read your camera manual and scratch his head (as many do), this brief introduction, in simple terms to help you make sense of openness and shutter priority.

Digital Photography: Aperture Priority and Priority Modes
October 15th, 2009Digital Photography: Accepting software on your life
October 14th, 2009Digital photography has created a shift in the balance between art and technology. No matter how you feel proud of your ability traditional camera, you also need to know much more about the software. As a wildlife photographer who grew up with movies, I like many others have been forced to change the way I see my role. In the past I knew that if I chose the best light for a subject, and applied my knowledge of the camera, usually produce the photo you want in the film. More importantly, it exposed the film always produces a high quality printing without the need for improvement. If they were unhappy with your photos, not groped to save with a computer, but are simply discarded. There are still many people my age that you see in the picture the same way. I was surprised to find that recently there have been many new photographers who still want to produce the perfect image in camera.They believe that traditional knowledge should be enough for the big picture, trust in the software shows a lack of capacity . In essence, a part of me appreciates this philosophy. After all, if the photos are more the product of their ability with a computer with a camera, you can really say that you're a good photographer? But here's the problem. Recently I was teaching a class that explains all the basics of good photography, aperture, shutter speed, depth of field, lighting, etc. One of the members of the class took me aside during a break with a question about some of the your photos. "I think there must be something wrong with my camera or my goal," he said. "I do not think that my photos are overexposed or underexposed. I do not think I used the wrong ISO, and I think that my photos are in focus. In fact I think I'm doing everything right. But the soft-looking photos that look flat … have no life. " I looked at the pictures and I had to accept. The problem was that he wanted to tell him what he was doing wrong with the camera. But if it was poorly lit, out of focus or poorly exposed, what could I say? The problem certainly was not with his digital SLR camera. In a class of fifteen people and at least a dozen digital cameras, his was the most advanced camera in the room. We transferred one of his photos on my computer. I opened in my editing software, and automatically adjust the contrast and saturation levels of the images. The result was immediate and dramatic. A photo that was flat and lifeless was suddenly rich and dimensional. The difference was even more evident when you take another look at the original image. Now, however, seemed a photocopy of poor quality. Here is a digital file containing all the information needed to produce a perfect image quality. The information should only be rearranged, using the software to make it. The software has become one of the essential ingredients of modern photography. While understandable that the old school of photographers looked on with disdain, the truth is that to some extent, the editing and improvement are simply part of the process. I'm not talking about using the software to produce a total image. This is certainly possible in those days. You can take a sky of a picture, put in the foreground behind the photo of another, moving objects and change colors, all with the click of a mouse. Will always be a matter of debate whether this is the true picture or not, I think, but you can disagree and you are entitled to their opinions. There can be no doubt, however, that this is something apart from capturing your photos using the traditional skills of the camera alone. No, what I'm talking about is to use the software to "tune" the image, to put it to a level that is comparable to film photography. You can often find this necessary to get the most from your camera, and not a reflection on his skills as a photographer. For ex-fashion photographers like me, this can be difficult to accept. But the first and swallow your pride and get to know your software a little 'better soon start producing the kind of picture you expect from your digital camera.
