C-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.
