The ABC of Photography – CMYK

Cyan, magenta, yellow and black (or ‘key’), the four primary inks used in commercial color printing. CMYK also refers to the printing process itself.

Collodion process This is an early technique for making photographic prints, invented by Frederick Scott Archer (1813-1857) in 1851, which used collodion (cellulose nitrate) to stick light-sensitive chemicals on the surface of a glass plate. The plate was exposed, developed and fixed while still wet. The process produced good results and was used widely until around 1880.

Colour cast A color tint in an image, caused by shooting in a particular kind of light. Tungsten light causes a yellow cast, while fluorescent light causes a green cast. Casts can be corrected using the camera’s white balance feature, or at the post-capture stage.
