What is a digital SLR camera?
SLR Cameras, or Single Lens Reflex, have a system whereby the image captured by the lens is exactly the same image that the photographer will see in the viewfinder and that will come out on film. This happens because of an image capture system made up of mirrors and camera prisms.
SLRs are professional analog cameras in which the photographer has full control to adjust the features available on the camera, such as white balance, aperture and others. Although the image quality of digital cameras is better, some photographers prefer SLR Cameras precisely because they have this control that allows “taking pictures” to become art and the complete work of those who handle the camera.
