Shutter: a device that allows light to pass for a determined period of time, for the purpose of exposing photographic film or a light-sensitive electronic sensor to light to capture a permanent image of a scene.
Exposure: controls the amount of light that enters the camera during a period of time.
Depth of field: the distance between the nearest and farthest objects in a scene that appear acceptably sharp in an image.
F-stop: the focal length divided by the "effective" aperture diameter.
Focal length: a measure of how strongly the system converges (focuses) or diverges (defocuses) light.
Lens: captures the light from the subject and brings it to a focus on the film or detector.
Focus: only objects within a limited range of distances from the camera will be reproduced clearly. The process of adjusting this range is known as changing the camera's focus.
