Panchromatic Emulsion
A black and white emulsion sensitised to all visible wavelengths, rendering colours as plausible grey tones.
Motion, Video & Creative TechniquesPanning
Following a moving subject with the camera during a relatively long exposure, so the subject stays sharp and the background streaks.
Post-Processing & RetouchingPanorama Stitching
Combining several overlapping frames into a single wider image by aligning and blending them.
Film, Darkroom & Historic ProcessesPaper Grade
A number describing the contrast of a graded photographic paper, from soft grade 0 to very hard grade 5.
Printing, Display & OutputPaper Profile
An ICC profile describing how a specific combination of printer, ink and paper reproduces colour.
Printing, Display & OutputPaper Weight
The mass of a paper per unit area, used as a rough indication of its substance and rigidity.
Focus & Depth of FieldParfocal Lens
A zoom lens that holds focus on the same subject as the focal length is changed.
Exposure & MeteringPartial Metering
A metering pattern reading roughly the central eight to fifteen per cent of the frame — broader than spot, narrower than centre-weighted.
Composition & Visual DesignPattern
A repeating arrangement of shapes, lines, colours or objects across the frame.
Cameras, Formats & SystemsPentamirror
A lighter, cheaper alternative to the pentaprism using a hollow arrangement of mirrors to perform the same image correction.
Cameras, Formats & SystemsPentaprism
A solid five-sided glass prism above an SLR's focusing screen that corrects the image left-to-right and presents it at eye level.
Colour & Colour ManagementPerceptual Rendering Intent
A conversion strategy that compresses the entire colour range so relationships between colours are preserved, at the cost of shifting every…
Composition & Visual DesignPerspective Compression
The apparent flattening of distance between near and far elements when photographing from far away with a long lens.
Post-Processing & RetouchingPerspective Correction
Digitally transforming an image to straighten converging verticals or horizontals.
Composition & Visual DesignPerspective Distortion
The exaggeration of relative size between near and far objects when photographing from very close with a wide lens.
Sensors & Digital CapturePhase-detect Pixel
A photosite masked on one side, or split in two, so it sees the scene through only part of the lens and can contribute to focus measurement.
Focus & Depth of FieldPhase-detection Autofocus
A focusing method that splits incoming light into two views and measures their separation to determine both the amount and direction of…
Printing, Display & OutputPhoto Black and Matte Black
Two distinct black inks formulated for glossy and matte papers respectively, only one of which can be active at a time on many printers.
Genres, Movements & TheoryPhoto Essay
A sequence of photographs arranged to develop an argument or narrative that no single image could carry.
Genres, Movements & TheoryPhoto-Secession
A group founded by Alfred Stieglitz in New York in 1902 to promote photography as a fine art.
Printing, Display & OutputPhotobook
A bound sequence of photographs designed to be read as a whole rather than viewed as individual prints.
Sensors & Digital CapturePhotodiode
The semiconductor junction within a photosite that converts arriving photons into electrical charge.
Film, Darkroom & Historic ProcessesPhotogram
An image made by placing objects directly on photographic paper and exposing it to light, without a camera.
Motion, Video & Creative TechniquesPhotogrammetry
Deriving three-dimensional measurements and models from a set of overlapping photographs.
