Learning Photography
There are 3 basic elements a photographer manipulates when taking a picture: subject, frame, and light. These three fundamental elements are what distinguish every photograph. The distinction between someone who takes pictures, and a photographer, is the ability to manipulate these three elements to create the desired image.
Exposure
Controlling the amount of brightness and darkness in an image
Shutter Speed and Motion
Manipulating the shutter speed to control motion in the frame.
Aperture and Focus
Utilizing the focus plane of an image.
