ICC Profile
A standardised data file describing how a device's colour numbers relate to absolute, measurable colour.
Exposure & MeteringIlluminance
The amount of light arriving on a surface per unit area, measured in lux, independent of what that surface does with it.
Optics, Lenses & FiltersImage Circle
The circular area of usable image a lens projects, which must be at least as large as the sensor's diagonal.
Files, Metadata & WorkflowImage Licensing
Granting specified rights to use an image while retaining ownership of the copyright.
Sensors & Digital CaptureImage Sensor
The silicon chip that converts light into an electrical signal, forming the digital equivalent of film.
Post-Processing & RetouchingImage Stacking
Averaging multiple identical exposures to reduce random noise or to combine content across frames.
Composition & Visual DesignImplied Motion
The suggestion of movement within a still image, created by blur, gesture, position or direction.
Motion, Video & Creative TechniquesIn-body Image Stabilisation
Stabilisation achieved by moving the sensor itself to counteract camera movement.
Exposure & MeteringIncident-light Metering
Measuring the light falling onto a subject rather than the light reflecting off it, using a handheld meter with a white diffusing dome.
Genres, Movements & TheoryIndexicality
The property of a photograph as a physical trace of light reflected from a real object, rather than a depiction made by hand.
Focus & Depth of FieldInfinity Focus
The lens setting at which parallel rays from very distant objects converge on the sensor.
Sensors & Digital CaptureInfrared Cut Filter
A filter bonded in front of the sensor that blocks infrared and ultraviolet light to which silicon is sensitive but the eye is not.
Film, Darkroom & Historic ProcessesInfrared Film
Film sensitised beyond the visible spectrum into the near infrared, producing distinctive tonal reversals.
Motion, Video & Creative TechniquesInfrared Photography
Photography using light beyond the visible red, producing distinctive tonal reversals and false-colour effects.
Files, Metadata & WorkflowIngest
The controlled process of copying images from a memory card into the working system, with verification and renaming.
Printing, Display & OutputInk Limit
The maximum total quantity of ink permitted in any one area, set to prevent flooding and bleeding.
Printing, Display & OutputInk Set
The complete group of ink colours a printer uses, including additional greys and extended-gamut colours beyond basic CMYK.
Printing, Display & OutputInkjet Printing
Printing by spraying microscopic droplets of ink onto paper, the dominant method for photographic and fine-art output.
Cameras, Formats & SystemsInstant Camera
A camera that exposes and develops a self-contained print within a minute of the shutter firing.
Motion, Video & Creative TechniquesIntentional Camera Movement
Deliberately moving the camera during a long exposure to abstract the scene into streaks and washes of colour.
Genres, Movements & TheoryInterior Photography
Photography of the inside of buildings, balancing artificial light, daylight and the character of a space.
Motion, Video & Creative TechniquesIntervalometer
A timer, built in or external, that fires the shutter automatically at set intervals for a set number of frames.
Motion, Video & Creative TechniquesIntra-frame Compression
Compression in which each frame is encoded independently, without reference to those around it.
Lighting & FlashInverse Square Law
The rule that light from a point source falls off in proportion to the square of the distance, so doubling the distance quarters the…
