A digital SLR, also known as a DSLR is a digital single lens reflex camera. Many people use smaller point and shoot style cameras where you view the image to be photographed on a small screen on the back of the camera. But a single reflex model allows you to look through a lens’ view finder.
These types of cameras are ideal for various types of photography because you can change the lenses on the camera body to suit the type of image you’d like to take. For instance, you can use wide-angle, fisheye, macro, zoom, and telephoto lenses etc., as you can simply interchange the lenses according to the situation.
You also have more control of the lighting conditions because you can light your subject by using accessories such as on camera flash, macro flashes, and radio slaves that utilize multiple flashes simultaneously.
