Photo 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 & Theory

Photo Essay

A sequence of photographs arranged to develop an argument or narrative that no single image could carry.

Genres, Movements & Theory

Photo-Secession

A group founded by Alfred Stieglitz in New York in 1902 to promote photography as a fine art.

Printing, Display & Output

Photobook

A bound sequence of photographs designed to be read as a whole rather than viewed as individual prints.

Sensors & Digital Capture

Photodiode

The semiconductor junction within a photosite that converts arriving photons into electrical charge.

e⁻ (electrons)
Film, Darkroom & Historic Processes

Photogram

An image made by placing objects directly on photographic paper and exposing it to light, without a camera.

Motion, Video & Creative Techniques

Photogrammetry

Deriving three-dimensional measurements and models from a set of overlapping photographs.

Genres, Movements & Theory

Photographic Ethics

The body of principles governing how photographers treat subjects, audiences and the truthfulness of their images.

Film, Darkroom & Historic Processes

Photographic Paper

Paper coated with a light-sensitive emulsion, used to make prints from negatives.

g/m²
Genres, Movements & Theory

Photographic Series

A set of images made to a consistent rule or format, where the repetition itself carries meaning.

Genres, Movements & Theory

Photographic Truth

The contested assumption that a photograph is a reliable record of what was in front of the camera.

Genres, Movements & Theory

Photojournalism

Photography made to report news, bound by professional standards of accuracy and non-interference.

Motion, Video & Creative Techniques

Photomicrography

Photography through a microscope, recording subjects at magnifications far beyond macro.

× magnification
Sensors & Digital Capture

Photosite

A single light-collecting element on a sensor, corresponding to one pixel in the final image.

Files, Metadata & Workflow

Pick Flag

A binary marker used during a first culling pass to separate keepers from rejects.

Genres, Movements & Theory

Pictorialism

A movement from the 1880s to the 1910s that sought recognition for photography as art by imitating painting and printmaking.

Printing, Display & Output

Pigment Ink

Ink in which the colourant is solid particles suspended in a carrier, sitting on the paper surface rather than dissolving into it.

Optics, Lenses & Filters

Pincushion Distortion

A geometric distortion in which straight lines bend inward toward the centre, pinching the frame corners outward.

%
Cameras, Formats & Systems

Pinhole Camera

A lensless camera that forms an image through a tiny aperture, giving infinite depth of field and extremely long exposures.

d = √(2 × λ × f) mm
Sensors & Digital Capture

Pixel Binning

Combining the signal from several adjacent photosites into one output pixel to improve signal-to-noise ratio.

SNR gain ≈ √n × (2×2, 4×4)
Files, Metadata & Workflow

Pixel Dimensions

The width and height of an image measured in pixels, which is its only fixed measure of size.

Total pixels = width × height px
Sensors & Digital Capture

Pixel Pitch

The centre-to-centre distance between adjacent photosites on a sensor.

Pitch = sensor width / horizontal pixels µm
Sensors & Digital Capture

Pixel Shift Multi-shot

A mode that moves the sensor by precise sub-pixel amounts between exposures and combines the frames into one higher-quality image.

count (4, 8, 16 frames)
Focus & Depth of Field

Plane of Focus

The flat surface, parallel to the sensor, at which the subject is rendered with maximum sharpness.
