a light-tight box containing light sensitive film or sensor that is used to make images.
information used by the computer, represented by numbers. The buzzword for any capture device that converts photons to electrons.
the viewing screen in an SLR on which composition takes place; may also contain various guides to exposure, focus, and flash-readiness.
___________have two primary functions: one is to focus light with as little distortion or aberration as possible on to film or sensor. The other function is to control the amount of light hitting the film by use of its aperture.
an exposure "mode" where the exposure system recommends a setting that is then made by the photographer by selecting aperture and shutter speeds manually. The booklet one doesn't read before using a piece of equipment.
known as a flash gun, strobe, or speedlight, it consists of a gas-filled tube that is fired by an electrical charge.
a flash that coordinates with the camera's exposure, and sometimes focusing systems.
a method of focusing where focusing distances are set automatically.
in exposure, when too much lighting strikes the film for a proper rendition of the scene.
the combination of aperture and shutter speed that yields a full-toned negative or slide that yields the best possible tonal representation of the scene onto film or sensor.
failure to expose correctly because not enough light has struck the film or sensor to faithfully render the color and brightness values.
a method of exposure where aperture and shutter speed settings are first read, then set, by the camera's exposure system.
the opening of a lens, the size of which is controlled by a diaphragm. The term is commonly used to designate f-stops, such as f/4, f/5.6 etc.
a series of numbers designating the apertures, or openings at which a lens is set. The higher the number, the narrower the aperture.
in a focal plane shutter, a set of curtains travels past the film gate and allows light to strike the film within a set period of time
with a shutter, the duration of time in which light strikes the film. With film, the sensitivity to light. With a lens, the maximum aperture
the zone, or range of distances within a scene that will record on film as sharp.
photos are divided into thirds with two imaginary lines vertically and two lines horizontally making three columns, three rows, and nine sections in the images.
part of scene or space around object that appears closest to camera. (2) element or feature of composition of photograph that is depicted as being nearest viewer.
the portion of a scene that sits behind the main, foreground subject.
