Digital SLR Cameras
Digital SLR (or DSLR ) Camera stands for single-lens reflex camera.
A digital SLR camera uses an automatic mirror system and pentaprism or pentamirror to direct light from the lens through the viewfinder eyepiece.
The basic operation of a Digital SLR Camera: for viewing purposes, the mirror reflects the light coming through the attached lens upwards at an approximately 90 degree angle. It is then reflected by the pentaprism to the photographer's eye. During exposure (when the photograph is taken), the mirror swings upward, and a shutter opens, allowing the lens to project light onto the image sensor.
The advantages of SLR cameras derive from viewing and focusing the image through the attached lens, providing a viewing image that will be exposed exactly as it is seen through the lens. Therefore digital SLR cameras give photographers precision and confidence.
Digital SLR Cameras used by professional and experienced amateur photographers.
