How the aperture setting, shutter speed, and

ISO sensitivity control exposure

The aperture setting, shutter speed, and ISO sensitivity are closely interconnected in

photography. The aperture setting controls the opening that regulates the light that enters

the camera, while the shutter speed determines the length of time that light is allowed to

enter. ISO sensitivity determines the speed at which the film reacts to light. Together, these

three aspects are described as the triangle of exposure.

A change in shutter speed, aperture value, or ISO sensitivity can be offset by adjustments to

the others to maintain the amount of light. The results, however, change according to the

settings. For example, shutter speed is useful in expressing movement, the aperture can

control the depth of field, and the ISO sensitivity can control the graininess of a photo.

Aperture value

Setting Result

Wide aperture = more light

Narrow aperture = less light

Wide = small depth of field

Narrow = large depth of field
