What is the difference between Program Mode (P), Aperture Priority Mode (A or AV), Shutter Priority Mode (S or TV), and Manual Mode (M)?
Program Mode automatically decides how much to freeze motion and how wide the distance from your camera you should see sharpness. However, it lets you control how much noise there will be.
Aperture Priority Mode (A or AV) is like Program Mode (P) except you can control how wide the distances of sharpness is away from the camera.
Shutter Priority Mode (S or TV) has one difference from Program Mode (P), it lets you control how much is froze.
These mentioned controls affect how much light there will be. This means that you cannot fully control how much light you get in your image unless you use the Manual Mode.
Manual allows you to fully control your camera, including all of these controls and more.
