Digital Photography Tricks – Revealing Your Digital SLR’s Secrets!
Few would argue that more people than ever can take pictures of real quality, as digital photography and the equipment available opens up opportunities for the keen amateur. Modern digital SLR cameras are boasting more and more megapixels and features, which can almost make photography seem too easy. However, there is functionality and easy to grasp techniques that many budding photographers never take advantage of. This article aims to address a few of the digital photography tricks and tools available.
Camera shake is the surest way to ruin a photograph, and can still occur even with your camera secured to a tripod. For example, you still have to press the shutter, and this causes some movement. This will ultimately affect the sharpness of your final image. There are two ways this can be avoided. The first is to use a remote control shutter release button, or the less expensive cable release alternative - both will do the job well. Otherwise, you can set your camera's self timer option. All that is required is that you set up the shot and settings, then stand back while the camera carries out the shutter press for you.
No matter how much care has been taken during the original shoot, most modern day photographers will carry out subsequent image manipulation. To give you the opportunity of making the most of this facility, it is always a good idea to shoot your original image in RAW rather than JPEG format. JPEG images contain 256 brightness levels in each of the three colour channels (red, green and blue). However, RAW files contain up to 16,384 levels, which means you can have much more influence when amending your image, for instance making significant changes to highlights or shadows.
One of the digital photography tricks to consider is using your SLR's Live View mode. Here you can set up your photo on the LCD monitor, rather than the viewfinder. One advantage to using this is the number of viewpoints you can use, for example, holding the camera above a crowd of people, and still being able to get an idea of what the final image will look like. Many people believe that it is easier to see the final composition by using Live View as opposed to the viewfinder.
Once upon a time, ISO was determined by the film you used. That is to say that you would be forced to stay with, for example, ISO 200 for all 36 shots if that was the film in the camera. However, with digital photography, you can adjust ISO for every picture you take, if necessary. Generally, an ISO setting of 640 or above can start to show some noise in your image. You need to consider the trade off between upping the ISO to allow shots in dark conditions, and accepting some noise, or missing the image altogether. In most cases, the auto ISO setting would work sufficiently.
These are just a few of the digital photography tricks that you can use, to help unravel the mysteries of your SLR.
I Have Heard Of SLR, But What Is A Digital SLR or dSLR?
When a photographer has a camera where the focus, composition, and depth of field are perfect, and they can be perfectly seen through the viewfinder in the same way as the photographer himself, nothing more needs to be said. With the lens being able to change according to the needs and desires of the photographer, there will be super freedom to take outstanding pictures.
What makes digital dSLRs so special? Just the fact they are the dSLR. The "single lens reflex camera" (dSLR) presently dominates the market for professional cameras. The other camera type is the rangefinders (RE) - their main difference with the dSLR is the way photographic scene is displayed, accessed, and processed in the viewfinder.
The main, fundamental principal of the dSLR is the TTL, or through-the-lens, mechanism. The earlier ones did not have today's "instant-return" mirror which we used today. Some advantages of the dSLR camera which caused it to move up on price, is the distance between the lens and film is increased due to needed space for the mirror, forcing the "retrofocus design" to be required, a special approach to the lens design.
The dSLR will give us a clearer and brighter image than any electronic viewfinder ever can. If a point and shoot (P&S) camera has a separate viewfinder, it will be much smaller than a dSLR and will not display any shooting data. The dSLR has a larger sensor in terms of physical size (not pixels), than a P&S camera. This is usually almost six times the area and this can significantly improve the image quality.
The main reason for this is that with a larger sensor, noise is less of a problem. Another benefit of having a larger sensor is that you can have a shallow depth of field for blurred background effects. A P&S camera with a higher pixel count than a dSLR may not provide images that are as good as the SLR.
There are many advantages of using the dSLR. Superior lens are one advantage while having the option of changing lenses is the other advantage. Using a macro lens with an SLR will give you better images than those provided by a P&S camera, with a macro facility.
Digital SLRs have a higher dynamic range than P&S cameras. Dynamic range refers to the brightness levels that a camera can capture. This is the range of light, from the lightest to the darkest, in which you can still make out the details.
In a dSLR the shutter lag is almost non-existent. This is the lag between the time when you press the button and when the photograph is taken. With an SLR, it may be as low as millionths of a second, while it may be much higher in a P&S camera. Most P&S cameras cannot capture images in the raw format, while all digital SLR cameras can.
Raw formats are images from the sensor that are saved without any manipulation by the camera's software. This can provide the best image quality that you can get from a digital camera.
However, a dSLR camera does have disadvantages. It costs a lot more, especially if you start adding the cost of the lenses and accessories. A digital SLR is also much bigger and heavier with the weight of the lens and accessories adding to the weight. Still, if you are interested in obtaining the best image quality, then a dSLR may be the best option for you.
