Caffenol is a photographic alternative process whereby phenols, sodium carbonate and optionally vitamin C are used in aqueous solution as a film and print photographic developer. [ 1 ] [ 2 ] Other basic (as opposed to acidic ) chemicals can be used in place of sodium carbonate; however, sodium carbonate is the most common.
In graphic art film, also called lithographic film which is a special type of black and white film used for converting images into halftone images for offset printing, a developer containing methol-hydroquinone and sulfite stabilizers may be used. Exposed silver halide oxidizes the hydroquinone, which then oxidizes a nucleating agent in the ...
Stieglitz was notable for introducing fine art photography into museum collections. Fine-art photography is photography created in line with the vision of the photographer as artist, using photography as a medium for creative expression. The goal of fine-art photography is to express an idea, a message, or an emotion.
The following outline is provided as an overview of and topical guide to photography: . Photography – process of making pictures by the action of recording light patterns, reflected or emitted from objects, on a photosensitive medium or an image sensor through a timed exposure.
Boulevard du Temple is a photograph of a Parisian streetscape made in 1838 (or possibly 1837 [1]), and is one of the earliest surviving daguerreotype plates produced by Louis Daguerre.

Weston photographed Pepper No. 30 using his Ansco 8×10 Commercial View camera with a Zeiss 21 cm lens. The smallest aperture on this lens is f /36. [citation needed] According to Weston's grandson Kim, it was shot at an aperture of f /240 with an exposure time of four to six hours. [5]
Alignment, in simple terms, is a change in the coordinates system so that it adopts a new coordinate system which outputs image matching the required viewpoint. The types of transformations an image may go through are pure translation, pure rotation, a similarity transform which includes translation, rotation and scaling of the image which ...
The Zone System is a photographic technique for determining optimal film exposure and development, formulated by Ansel Adams and Fred Archer. [1] Adams described the Zone System as "[...] not an invention of mine; it is a codification of the principles of sensitometry, worked out by Fred Archer and myself at the Art Center School in Los Angeles, around 1939–40."
