Contact 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.
Post-Processing & RetouchingContent-aware Fill
A tool that removes a selected area and synthesises a replacement from surrounding image content.
Lighting & FlashContinuous Lighting
Lighting that stays on constantly rather than firing a brief burst, so its effect is visible before exposure.
Focus & Depth of FieldContinuous-servo Autofocus
An autofocus mode, marked AF-C or AI Servo, that keeps adjusting focus for as long as the button is held.
Post-Processing & RetouchingContrast Adjustment
A control that increases or decreases the difference between light and dark tones across the whole image.
Film, Darkroom & Historic ProcessesContrast Index
A measure of the average slope of a film's characteristic curve over the range actually used in practice.
Focus & Depth of FieldContrast-detection Autofocus
A focusing method that drives the lens back and forth, measuring image contrast, and settles at the point of maximum contrast.
Composition & Visual DesignConverging Verticals
The apparent leaning-together of vertical lines when the camera is tilted up or down.
Files, Metadata & WorkflowCopyright Metadata
The metadata fields asserting authorship, copyright status and usage terms for an image.
Printing, Display & OutputCotton Rag Paper
Paper made entirely from cotton fibre, with no wood pulp, giving high permanence and a soft matte surface.
Cameras, Formats & SystemsCrop Factor
The ratio between a sensor's diagonal and that of full frame, used to convert focal lengths into their full-frame equivalents.
Composition & Visual DesignCropping
Removing part of an image after capture to change its framing, proportion or emphasis.
Film, Darkroom & Historic ProcessesCross-processing
Deliberately developing film in chemistry intended for a different process, producing extreme colour and contrast shifts.
Focus & Depth of FieldCross-type AF Point
A phase-detection point sensitive to detail running in both horizontal and vertical directions.
Exposure & MeteringCrushed Blacks
Shadow areas pushed to pure black so that separation between dark tones is lost.
Lighting & FlashCTO Gel
A colour temperature orange gel that warms a daylight-balanced source to match tungsten light.
Files, Metadata & WorkflowCulling
The process of reviewing a shoot and selecting which frames are worth keeping and editing.
Post-Processing & RetouchingCurves
A tonal adjustment that maps input brightness values to output values along a freely shaped line.
Colour & Colour ManagementCustom White Balance
Setting white balance by photographing a known neutral target under the actual light and telling the camera to treat it as neutral.
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.
Sensors & Digital CaptureDark Current
Charge that accumulates in a photosite from thermal energy rather than from light, growing with exposure time and temperature.
Sensors & Digital CaptureDark Frame
An exposure made with the shutter closed, at the same duration, temperature and ISO as the real image, used to characterise sensor noise.
