Agitation
The periodic movement of the developing tank that replenishes fresh chemistry at the emulsion surface.
Film, Darkroom & Historic ProcessesAlbumen Print
A printing process using egg white to bind light-sensitive silver salts to paper, giving a glossy surface and warm brown tones.
Film, Darkroom & Historic ProcessesAutochrome
The first commercially successful colour process, using a screen of dyed potato starch grains over a black and white emulsion.
Film, Darkroom & Historic ProcessesBlack and White Film
Film with a single silver-based emulsion that records only luminance, producing a monochrome negative.
Film, Darkroom & Historic ProcessesBurning
Giving extra exposure to part of a print so that area comes out darker.
Film, Darkroom & Historic ProcessesC-41 Process
The standardised chemical process for developing colour negative film.
Film, Darkroom & Historic ProcessesCalotype
An early paper-negative process, patented by Fox Talbot in 1841, allowing multiple prints from one exposure.
Film, Darkroom & Historic ProcessesCamera Obscura
A darkened room or box in which a small aperture projects an inverted image of the outside world onto an inner surface.
Film, Darkroom & Historic ProcessesCharacteristic Curve
A graph plotting a film's resulting density against the logarithm of the exposure it received.
Film, Darkroom & Historic ProcessesChromogenic Black and White Film
A monochrome film that forms its image from dye couplers rather than silver, and is processed in standard colour chemistry.
Film, Darkroom & Historic ProcessesColour Negative Film
Film that records a colour image with tones and colours inverted, printed or scanned to produce a positive.
Film, Darkroom & Historic ProcessesColour Reversal Film
Film that produces a positive transparency directly, viewable and projectable without printing.
Film, Darkroom & Historic ProcessesContact Print
A print made with the negative in direct contact with the paper, producing an image the same size as the negative.
Film, Darkroom & Historic ProcessesContact Sheet
A print made by laying an entire strip or roll of negatives directly on paper, showing every frame at negative size.
Film, Darkroom & Historic ProcessesContrast Index
A measure of the average slope of a film's characteristic curve over the range actually used in practice.
Film, Darkroom & Historic ProcessesCross-processing
Deliberately developing film in chemistry intended for a different process, producing extreme colour and contrast shifts.
Film, Darkroom & Historic ProcessesCyanotype
An iron-based printing process producing images in Prussian blue, developed simply by washing in water.
Film, Darkroom & Historic ProcessesDaguerreotype
The first commercially successful photographic process, producing a unique, highly detailed image on a polished silvered copper plate.
Film, Darkroom & Historic ProcessesDarkroom
A light-tight room equipped for processing film and making prints.
Film, Darkroom & Historic ProcessesDensitometer
An instrument that measures the optical density of a negative, transparency or print.
Film, Darkroom & Historic ProcessesDensity
A measure of how much light a processed negative or print blocks, expressed logarithmically.
Film, Darkroom & Historic ProcessesDeveloper
The chemical solution that converts exposed silver halide crystals into metallic silver, making the latent image visible.
Film, Darkroom & Historic ProcessesDodging
Holding back light from part of a print during exposure so that area comes out lighter.
Film, Darkroom & Historic ProcessesDX Coding
The pattern of conductive and insulating squares on a 35 mm cassette that tells the camera the film's speed and length.
