Third Stop
A one-third-stop increment, the fine adjustment step most digital cameras use for aperture, shutter speed, ISO and exposure compensation.
Focus & Depth of FieldZone Focusing
Presetting a lens to a distance and aperture whose depth of field covers the range the subject will occupy, then shooting without focusing…
Optics, Lenses & FiltersAspherical Element
A lens element whose surface departs from a simple sphere, correcting aberrations that spherical glass cannot.
Exposure & MeteringAuto ISO
A camera mode that lets the body select sensitivity automatically within limits the photographer sets, usually with a minimum shutter speed.
Optics, Lenses & FiltersBokeh
The aesthetic character of the out-of-focus areas of an image, as distinct from how much of the image is out of focus.
Optics, Lenses & FiltersCat's-eye Bokeh
The lens-shaped, off-round rendering of out-of-focus highlights near the frame corners, caused by optical vignetting.
Optics, Lenses & FiltersCatadioptric (Mirror) Lens
A long lens that folds its light path with curved mirrors as well as glass, achieving great focal length in a short, light barrel.
Optics, Lenses & FiltersComa
An aberration that renders off-axis points of light as asymmetric comet-shaped smears rather than dots.
Cameras, Formats & SystemsCrop Factor
The ratio between a sensor's diagonal and that of full frame, used to convert focal lengths into their full-frame equivalents.
Focus & Depth of FieldDeep Depth of Field
A wide zone of sharpness in which foreground, subject and background all hold detail.
Focus & Depth of FieldDepth of Field
The range of distances in front of and behind the plane of focus that appears acceptably sharp in the final image.
Cameras, Formats & SystemsEquivalent Focal Length
The full-frame focal length that would give the same angle of view as a given lens on a smaller format.
Files, Metadata & WorkflowEXIF
The standard block of technical metadata a camera writes into a file, recording settings and equipment.
Exposure & MeteringExposure Compensation
A deliberate offset applied to the camera's metered reading, expressed in stops, to make an image brighter or darker than the meter…
Focus & Depth of FieldEye AF
A refinement of face detection that locates and focuses on the eye itself, and usually lets the photographer choose which one.
Sensors & Digital CaptureFlat Field Correction
Dividing an image by a frame of evenly illuminated field to remove vignetting, dust shadows and photosite sensitivity variation.
Focus & Depth of FieldFocus Confirmation
An indicator, usually a dot or the illumination of an AF point, showing that the camera considers focus achieved.
Focus & Depth of FieldFocus Peaking
A display aid that outlines the highest-contrast edges in the live image, marking what is currently in focus.
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.
Genres, Movements & TheoryGroup f/64
A short-lived association of West Coast American photographers formed in 1932 to advocate sharp, unmanipulated photography.
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.
Cameras, Formats & SystemsLens Adapter
A ring or unit that lets a lens designed for one mount be fitted to a body with a different one.
Post-Processing & RetouchingLens Correction Profile
A stored description of a lens's distortion, vignetting and chromatic aberration, applied automatically during processing.
Optics, Lenses & FiltersLens Flare
Stray light scattered inside a lens by a bright source, appearing as streaks, polygons or a general wash across the image.
