Indexicality
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…
Files, Metadata & WorkflowIPTC
A metadata standard developed for the press, holding descriptive and rights information such as caption, creator, keywords and copyright.
Exposure & MeteringISO
The standardised measure of how strongly a camera amplifies the signal it captures, determining image brightness for a given exposure.
Sensors & Digital CaptureISO Invariance
The property of a sensor whose noise is essentially the same whether a file is brightened by raising ISO in camera or by lifting exposure…
Composition & Visual DesignIsolation
Separating a subject from its surroundings so it reads alone, using depth of field, framing, tone or timing.
Motion, Video & Creative TechniquesJib
A counterweighted arm that raises and sweeps a camera through an arc, giving elevation and movement from a fixed base.
Files, Metadata & WorkflowJPEG
The dominant lossy image format, using frequency-domain compression to achieve small files at the cost of some quality.
Files, Metadata & WorkflowJPEG XL
A newer image format offering both lossy and lossless compression, high bit depth, and lossless recompression of existing JPEGs.
Composition & Visual DesignJuxtaposition
Placing two contrasting or unexpectedly related elements together in a frame so each comments on the other.
Colour & Colour ManagementKelvin Scale
The absolute temperature scale used to state the colour of light sources and white balance settings.
