Degradation of a material caused by exposure to light, specifically the chemical changes to photodegradable molecules induced by absorption of photons, especially those wavelengths found in sunlight.

Objects in a variety of forms designed to hold photographs for presentation or storage. These range from simple folders that incorporate a passe-partout to more elaborate frame-like constructions, or bindings.

Devices used to steady the head of photographic sitters when long exposures are necessary for formal portraits, to prevent blurring the image. These have been rendered mostly obsolete as photographic technologies have advanced.

Ancillary devices, equipment, parts, and supplies used in the practice of making photographs, and that play an auxiliary role or facilitating the production of photographic images, including maintenance equipment and studio equipment.

Backdrops intended specifically to appear behind the subjects of photographs. These may be elaborately painted, or simply fields of texture or color, and appear in a variety of materials.

Instruments that measure the optical density of areas of photographic film or paper, for color saturation and to calibrate print equipment, and generally to make adjustments for quality control.

Containers specially designed to protect and transport one or more items of photographic equipment.

Books that are illustrated by mounting original photographs on the printed page, dating to after the invention of photography in the late 1830s but before photomechanical illustrations became the standard for print media later in the 1800s.

Communications field concerned with using photographs to document significant events, often in the context of news and related commentary through the mass media, both print and electronic. For journalism focusing on images other than photographs, use "pictorial journalism."

Artists who create photomontages, which are combinations of photographic images, or of photographic and other images such as architectural drawings, usually arranged into a somewhat unified image.

A branch of physics that deals with the properties and applications of photons especially as a medium for transmitting information.

Refers to light-induced oxidation.

Una fotocopiadora de proyección temprana creada en la década de 1900 por la Commercial Camera Company, que se convirtió en Photostat Corporation. El nombre "Photostat" era originalmente una marca comercial de la compañía, que luego se convirtió en término genérico y se usaba a menudo para referirse a máquinas similares producidas por Rectigraph Company.

Copias realizadas en una fotocopiadora de proyección temprana particular creada en la primera década del siglo XX por la Commercial Camera Company, que luego se convirtió en Photostat Corporation. El nombre "Photostat" era originalmente una marca comercial de la compañía, que luego se convirtió en término genérico y se usaba a menudo para referirse a máquinas similares producidas por Rectigraph Company.

Continuous tone color prints created by the thermal development of light-sensitive materials to transfer a latent image onto print media. The process is marketed as 'Pictrography' by Fuji Photo Film Co. Ltd.

Genus containing 1 to 4 species (depending upon the classification) of large perennial grasses found in wetlands throughout temperate and tropical regions of the world.

Species of broad-leafed grass, about 1.5 to 5 m (5 to 16.5 feet) in height, with feathery flower clusters and stiff, smooth stems, occurring along the margins of lakes, fens, marshes, and streams from the Arctic to the tropics. It is one of the most widely distributed plants in the world, with fruits borne in parachute-like containers that are carried by the wind. It is also one of the most successful plants in dominating appropriate habitats due to rhizomes that rapidly infest moist-to-saturated soils of swamps, ponds, streams, and banks to the eventual exclusion of almost all other plants. Dried stems have been used for millennia as thatching and construction material, in basketry, for arrows, pens, and musical instruments. They also are harvested for their cellulose content.
