What is an SLR digital Camera? How does it differ from a normal digital one?
SLR cameras let you see through lens by a viewfinder. The mirror behind the lense reflects the image back to the viewfinder, and when you press the shutter release button, the mirror flips away to reveal a sensor and the picture is taken. SLR differs from point-and-shoot from the option to use manual controls. They give you total control of how you want to compose your picture. You can control the depth of field and amount of light entering by changing the aperature, and you can freeze motion or blur it by setting the shutter sheed. But for people not familiar with manual controls, there is a auto function and you can snap pictures just as easily as a normal camera. Another major difference is that the shutter lag on an SLR is almost non existant compared to a point and shoot which can take a few seconds to finally capture a picture. SLR cameras have better photo quality because of the sensor size. I have heard somewhere that the sensor on a point-and-shoot is 1/16th the size of an SLR
