Relative Colorimetric Intent
A conversion strategy that reproduces in-gamut colours exactly and clips out-of-gamut ones to the nearest reproducible value.
Focus & Depth of FieldRelease Priority
A setting that fires the shutter whenever the button is pressed, regardless of whether focus has been confirmed.
Lighting & FlashRembrandt Lighting
A portrait pattern in which a small triangle of light appears on the shadowed cheek, below the eye.
Colour & Colour ManagementRendering Intent
The strategy chosen for handling colours that fall outside the destination gamut during a colour space conversion.
Film, Darkroom & Historic ProcessesResin-coated Paper
Photographic paper sealed between thin polyethylene layers so chemistry cannot penetrate the base.
Optics, Lenses & FiltersResolving Power
The finest detail a lens or film can distinguish, traditionally expressed in line pairs per millimetre.
Optics, Lenses & FiltersRetrofocus Design
A wide-angle design with a negative front group that places the rear element further from the sensor than the focal length would allow.
Exposure & MeteringRGB Histogram
Three separate histograms, one per colour channel, revealing clipping that a combined luminance histogram would hide.
Lighting & FlashRim Light
A light placed behind and to one side of the subject that draws a bright edge along its outline, separating it from the background.
Lighting & FlashRing Flash
A flash tube arranged in a circle around the lens, producing nearly shadowless frontal light.
Sensors & Digital CaptureRolling Shutter Artefact
Distortion caused by a sensor being read out progressively, so different parts of the frame record at slightly different times.
Files, Metadata & WorkflowRound-trip Editing
Sending an image from a catalogue to an external editor and returning the result automatically to the same collection.
Composition & Visual DesignRule of Odds
The observation that an odd number of subjects in a frame usually reads as more settled than an even number.
Composition & Visual DesignRule of Space
The guideline that a subject which is moving or looking in a direction should have space in front of it within the frame.
Composition & Visual DesignRule of Thirds
A guideline that divides the frame into nine equal parts and suggests placing key elements along those lines or at their intersections.
