Back Focus
A calibration error in which a lens consistently focuses slightly beyond the intended subject.
Focus & Depth of FieldBack-button Focus
A configuration that moves autofocus activation from the shutter release to a separate rear button.
Lighting & FlashBackground Light
A light aimed at the backdrop rather than the subject, controlling how bright or dark the background renders.
Lighting & FlashBacklighting
Placing the main light source behind the subject, so it faces the camera rather than illuminating the subject's front.
Sensors & Digital CaptureBackside-illuminated Sensor
A sensor design in which the wiring layer is moved behind the photodiodes so light reaches them unobstructed.
Files, Metadata & WorkflowBackup
A separate copy of image files kept so that loss of the original does not lose the work.
Cameras, Formats & SystemsBall Head
A tripod head using a single ball-and-socket joint, allowing the camera to be aimed in any direction with one locking knob.
Sensors & Digital CaptureBanding Noise
Horizontal or vertical stripes appearing in heavily lifted shadows, caused by variations between readout channels.
Lighting & FlashBarn Doors
Four hinged flaps mounted on the front of a light to cut its beam into a rectangle.
Optics, Lenses & FiltersBarrel Distortion
A geometric distortion in which straight lines bow outward from the centre, as if the image were wrapped around a barrel.
Printing, Display & OutputBaryta Paper
An inkjet paper coated with barium sulphate, imitating the surface and depth of traditional darkroom fibre-based paper.
Exposure & MeteringBase ISO
The sensitivity at which a sensor is read out with no amplification, delivering its maximum dynamic range and cleanest files.
Files, Metadata & WorkflowBatch Rename
Renaming many files at once using a template built from metadata, sequence numbers and fixed text.
Cameras, Formats & SystemsBattery Grip
An accessory that bolts to the base of a camera to hold additional batteries and duplicate the controls for vertical shooting.
Sensors & Digital CaptureBayer Filter
The dominant colour filter array pattern, using two green filters for every red and blue in a repeating square of four.
Lighting & FlashBeauty Dish
A shallow metal parabolic reflector with a central deflector, producing light that is soft in transition yet crisp in its specular…
Exposure & MeteringBellows Extension Factor
The extra exposure required when a lens is racked far forward for close focus, spreading its light over a greater distance.
Composition & Visual DesignBird's-eye View
A viewpoint directly overhead, looking straight down, which renders a scene as a flat pattern.
Files, Metadata & WorkflowBit Rot
The gradual, silent corruption of stored data over time, in which individual bits change without any error being reported.
Motion, Video & Creative TechniquesBitrate
The quantity of data used per second of video, which largely determines its quality within a given codec.
Files, Metadata & WorkflowBits per Channel
The number of bits used to record each colour channel of a pixel, determining how many tonal levels are available.
Post-Processing & RetouchingBlack and White Conversion
Turning a colour image into monochrome by mapping each colour to a chosen grey value.
Film, Darkroom & Historic ProcessesBlack and White Film
Film with a single silver-based emulsion that records only luminance, producing a monochrome negative.
Sensors & Digital CaptureBlack Level
The numerical value a sensor reports for a completely unexposed photosite, subtracted during processing to establish true black.
