'''Exposure''' is the amount of light needed to form an image. This is measured with a light meter that is built into the SLR camera. It turns on immediately when the camera is switched on. The light meter sensitivity is adjusted by the ISO settings (ISO means: International Standards Organization). ISO is also sometimes referred to as ISO Ratings.
