From Wikipedia, the free encyclopedia
The Exposure triangle is a visual and theoretical understanding of the three main variables required to obtain an exposure. Shutter speed, Aperture and ISO each individually effect the final exposure. The correct balance of these variables produces a properly exposed image. It is very important that a photographer has a strong understanding of the exposure triangle as it is the base fundamental principal of the creation of every image. Understanding the exposure triangle allows the photographer to create a correctly exposed image [1]

The exposure triangle is made up of three elements shutter speed, aperture and ISO. [2] Aperture is the opening in the lens which controls the amount of light that comes through the lens. Aperture also controls the depth of field. Shutter speed controls the duration the sensor of the camera is open to light. ISO is the sensitivity of the camera’s sensor to light. [3] The balance of these three variables allow the photographer to obtain the exposure they want. [4]
