What is the difference between DSLR and Point and Shoot Cameras?
There are several differences between DSLR and Point and Shoot cameras.
Digital Single Lens Reflex (DSLR) is a professional level camera that has a mirror behind the lens to enable the photographer to view the object and adjust the image according to what he wants to capture and then after composing the shot, click it to save it on a memory chip/card instead of film whereas Point and Shoot cameras are simple cameras that enable the photographer to just aim the camera with the automatic point part and press the button with the shoot part of the camera.
DSLR have interchangeable lens to accommodate different shooting situations whereas Point and Shoot cameras have no such lenses.
DSLR are heavy cameras and need accessories to capture an image whereas Point and Shoot cameras are very small and handy and can even be accommodated in your pocket.
DSLR are professional level cameras thus have large sensors producing high quality image whereas the Point and Shoot cameras have small sensors making them unable to capture a large area. The quality of the image is also not very high.
