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.
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.
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).
