Camera Parts

The aperture stop of a photographic lens can be adjusted to control the amount of light reaching the film or image sensor. Shutter speed or exposure time is the length of time a camera's shutter is open when taking a photograph. Exposure is the amount of light allowed to fall on each area unit of a photographic medium (photographic film or image sensor) during the process of taking a photograph. Depth of field (DOF) is the distance between the nearest and farthest objects in a scene that appear acceptably sharp in an image. The f-number (sometimes called focal ratio, f-ratio, f-stop, or relative aperture) of an optical system is the ratio of the lens's focal length to the diameter of the entrance pupil. The focal length of an optical system is a measure of how strongly the system converges or diverges light.
