Focus Shift
A movement of the plane of sharpest focus as a lens is stopped down, caused by residual spherical aberration.
Focus & Depth of FieldFocus Stacking
Combining several frames focused at different distances into one image with depth of field no single exposure could achieve.
Focus & Depth of FieldFocus Throw
The angle through which a focus ring must turn to travel from minimum distance to infinity.
Focus & Depth of FieldFocus-by-wire
A manual focus ring that sends an electronic signal to a motor rather than moving the optics mechanically.
Files, Metadata & WorkflowFolder Structure
The hierarchy of directories in which image files are physically stored.
Motion, Video & Creative TechniquesFollow Focus
A geared mechanism that allows focus to be adjusted precisely and repeatably, usually by a second operator.
Genres, Movements & TheoryFood Photography
Photography of prepared food, for menus, packaging, editorial and cookbooks.
Composition & Visual DesignForeground Interest
An element placed close to the camera to anchor the composition and establish depth.
Files, Metadata & WorkflowFormat Migration
Converting archived files to a current format before the original becomes unreadable.
Sensors & Digital CaptureFoveon Sensor
A sensor that records all three colours at every location by stacking three photodiode layers at different depths in the silicon.
Motion, Video & Creative TechniquesFPV Drone
A first-person-view drone flown through a headset showing the pilot's live camera feed, capable of fast, acrobatic movement.
Motion, Video & Creative TechniquesFrame Rate
The number of individual frames recorded or played back per second.
Composition & Visual DesignFrame Within a Frame
Using an element in the scene — a doorway, arch, window or overhanging branch — to surround and isolate the subject.
Printing, Display & OutputFraming Glass
The transparent glazing that protects a framed print, available in grades differing in reflection and ultraviolet filtering.
Motion, Video & Creative TechniquesFreelensing
Detaching a lens from the camera and holding it in front of the mount, tilting it to create selective focus and light leaks.
Post-Processing & RetouchingFrequency Separation
A retouching technique that splits an image into a blurred low-frequency layer of tone and colour and a high-frequency layer of texture.
Focus & Depth of FieldFront Focus
A calibration error in which a lens consistently focuses slightly nearer than the intended subject.
Cameras, Formats & SystemsFull Frame
A sensor the same size as a 35 mm film negative, 36 by 24 millimetres, treated as the reference format for focal length and depth of field.
Sensors & Digital CaptureFull-well Capacity
The maximum number of electrons a photosite can hold before it saturates and stops responding to further light.
