Camera functions

ISO –

The ISO is the level of sensitivity of your camera to light. Higher ISO means more sensitivity to light (more noise), lower ISO means less sensitivity (less noise).

Shutter speed –

The duration for which the aperture will remain open. On an SLR camera the shutter speed can be adjusted. The numbers represent either seconds or fractions of a second.

Aperture –

A variable opening inside a lens that regulates the amount of light reaching the image plane. Also known as an iris. The bigger the Aperture the more light comes in.

Focusing ring –

The band on the camera lens that when turned, moves the lens in relation to the film plane, focusing the camera for specific distances.

Exposure –

The amount of light per unit area (the image plane illuminance times the exposure time). The ‘exposure triangle’ is determined by shutter speed, lens aperture and light sensitivity (ISO).
