Highlight Recovery
The reconstruction of detail in bright areas where one or two colour channels have clipped but at least one has not.
Exposure & MeteringHighlight-weighted Metering
A metering pattern that biases exposure toward protecting the brightest area of the frame from clipping.
Exposure & MeteringHistogram
A graph of how many pixels in an image fall at each brightness level, from black on the left to white on the right.
Motion, Video & Creative TechniquesHoly Grail Transition
A time-lapse that runs across a large change in light, such as day into night, requiring exposure to change during the sequence.
Lighting & FlashHoneycomb Grid
A cellular insert placed over a light that narrows its beam by absorbing rays travelling at wide angles.
Composition & Visual DesignHorizon Line
The line where sky meets land or sea, which in a photograph always sits at the camera's own eye level.
Sensors & Digital CaptureHot Pixel
A photosite with abnormally high dark current that records as a bright coloured dot in long exposures.
Cameras, Formats & SystemsHot Shoe
The standardised bracket on top of a camera that both holds an accessory and provides electrical contacts to trigger it.
Colour & Colour ManagementHSL
A colour model describing colour by hue, saturation and lightness, widely used for targeted colour editing.
Colour & Colour ManagementHue
The attribute of a colour that gives it its name — red, green, blue — represented as a position on a circular scale.
Genres, Movements & TheoryHumanist Photography
A postwar movement, strongest in France, that photographed ordinary life with warmth and an emphasis on shared human experience.
Focus & Depth of FieldHybrid Autofocus
A system combining phase detection for speed and direction with contrast detection for final precision.
Cameras, Formats & SystemsHybrid Viewfinder
A finder that can switch between an optical view and an electronic one, or overlay electronic information on the optical image.
Focus & Depth of FieldHyperfocal Distance
The focus distance that yields the greatest depth of field, extending from half that distance out to infinity.
Motion, Video & Creative TechniquesHyperlapse
A time-lapse in which the camera moves substantially between frames, producing accelerated motion through space.
Colour & Colour ManagementICC 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.
