The information is filtered from light rays that meet the retina. The light is called the stimulus energy or sensation. The information consists of underlying patterns or 'invariants' for vital features to the environment. Gibson's view of depiction concerns the re-presentation of these invariants.
The American Standards Association (now called the American National Standards Institute, ANSI) defined the ASA system for rating the speed sensitivity of photographic emulsions; now superseded by the ISO system.

Photographic lighting refers to how a light source, artificial or natural, illuminates the scene or subject that is photographed; put simply, it is lighting in regards to photography. Photographers can manipulate the positioning and the quality of a light source to create visual effects , potentially changing aspects of the photograph such as ...
Also called available light. Any source of light that is not explicitly supplied by the cinematographer. The term usually refers to sources of light that are already "available" naturally (e.g. the Sun, Moon, lightning) or artificial light that is already being used (e.g. to light a room).

In lighting for film, theatre and still photography, a cucoloris (occasionally also spelled cuculoris, kookaloris, cookaloris or cucalorus) is a light modifier (tool, device) for casting shadows or silhouettes to produce patterned illumination.
The word "photography" was created from the Greek roots φωτός (phōtós), genitive of φῶς (phōs), "light" [2] and γραφή (graphé) "representation by means of lines" or "drawing", [3] together meaning "drawing with light". [4] Several people may have coined the same new term from these roots independently.
Abstract photography, sometimes called non-objective, experimental or conceptual photography, is a means of depicting a visual image that does not have an immediate association with the object world and that has been created through the use of photographic equipment, processes or materials.
The sensitivity to light, of the medium—the film or the digital camera sensor—is important in landscape photography, especially where great detail is required. In bright daylight, a "slow film" (low- ISO film), or low-ISO digital camera sensor sensitivity setting (typically ISO 100, or perhaps 200), is generally preferred, allowing maximum ...
