Starting Digital Photography?

If you have recently bought a digital SLR camera or if you are thinking about buying one, then read on.

Moving from the automatic settings of a small format camera to the manual settings of a dSLR (digital single lens reflex) can sometimes seem a lot of work, particularly when the 'auto' mode already produces great looking photographs.

However, you will soon discover that dSLR (digital single lens reflex) photograpy will reward you with creative photographs that are so much clearer, sharper and more beautiful than you would have ever believed possible.

Why are dSLR cameras better?

I enjoyed using my little compact point and shoot camera (a Kodak Z710) for a few years before becoming totally frustrated with the poor quality of the shots. A man in a camera shop explained why even in perfect light I couldn't get the shots I wanted. He said that even if you have an expensive point and shoot camera it simply will not compete with dSLR because the pixels on the sensor chip are so much smaller than the pixels on a dSLR. Because the compact camera has to amplify the signal so much more to compensate for the size of the sensor, the 'noise' is much greater than a dSLR at the same ISO.

Because of this compact cameras have to work at much slower speeds to get anywhere close to a good shot. Slower speeds mean blurred photos. If you want really crisp arresting images, you have to step up to dSLR. This may not mean going up in price as some point-and-click cameras actually cost more than dSLRs.

Size of Camera Sensor

A digital SLR camera sensor (CMOS) is around 15x15 = 225mm square

As a result, the ammount of light reaching the sensor in a digital SLR is so much more than most compact cameras, leading to much higher quality images, pretty much regardless of the number of megapixels.
