When you are searching for a camera, you will encounter many styles. Technical names like "SLR" may intimidate you, but they don't have to.
Definition
Prior to the advent of digital cameras there were two basic types of camera on the market. The single lens reflex camera and the twin lens reflex camera. The SLR uses mirrors to allow the photographer to view the image through the single lens that captures the image for a more accurate photo.
Advantages
Because SLR cameras allow you to see the photo as it will look when taken through the same lens, the photographer can make minute adjustments to the camera for the best possible photo.
Features
Some other features offered in the SLR cameras include through-the-lens metering, dedicated flash control and the ability to change lenses on the camera.
Technology
The image-capturing plane (formerly a strip of film) is a light-sensitive computerized chip, known as a charge-coupled device, or CCD. This rests behind a mirror and a shutter that blocks out all light from the lens.
WYSIWYG
The image in the viewfinder is actually the reflection of the image that travels through the camera lens and bounces off of three angled mirrors.
Mechanics
When you are ready to take a picture, the primary mirror lifts for a fraction of a second--just long enough for the CCD to capture the image.
Considerations
It is important to keep your digital camera clean. Because the CCD is electrified, dust will stick to it and show up on your images.
