Export Preset

A saved combination of export settings applied in one action to ensure consistency and avoid errors.

Exposure & Metering

Exposing to the Right (ETTR)

The technique of exposing as brightly as possible without clipping, then darkening in processing to maximise signal-to-noise ratio.

stops (EV)
Exposure & Metering

Exposure

The total amount of light that reaches the sensor or film, set by the combination of aperture, shutter speed and the scene's brightness.

H = E × t lux-seconds (lx·s)
Post-Processing & Retouching

Exposure Adjustment

A processing control that brightens or darkens the whole image in stops, mimicking a change in camera exposure.

stops (EV)
Exposure & Metering

Exposure Compensation

A deliberate offset applied to the camera's metered reading, expressed in stops, to make an image brighter or darker than the meter…

Setting = Metered EV − Compensation stops (EV)
Post-Processing & Retouching

Exposure Fusion

Blending bracketed frames directly into a normal-range image by selecting the best-exposed pixels, without building an HDR file first.

count
Exposure & Metering

Exposure Latitude

How far an exposure can miss the ideal and still produce an acceptable image after processing.

stops
Exposure & Metering

Exposure Simulation

A live-view or electronic-viewfinder mode that displays the scene at the brightness the current settings will actually record.

Exposure & Metering

Exposure Triangle

The teaching model that links aperture, shutter speed and ISO as three interdependent controls, where changing one requires compensating…

Aperture ↔ Shutter ↔ ISO stops
Exposure & Metering

Exposure Value (EV)

A single number describing every combination of aperture and shutter speed that produces the same exposure.

EV = log₂(N² / t) EV
Exposure & Metering

Extended ISO

ISO settings outside a sensor's native range, marked with an L or H prefix, that are produced by digital manipulation rather than analogue…

ISO
Optics, Lenses & Filters

Extension Tube

A hollow spacer placed between lens and camera that shortens the minimum focus distance and increases magnification.

m_added = extension / f mm
Focus & Depth of Field

Eye AF

A refinement of face detection that locates and focuses on the eye itself, and usually lets the photographer choose which one.

Exposure & Metering

F-number

The ratio of a lens's focal length to the diameter of its entrance pupil, written f/2.8, f/8 and so on, and the standard way of stating…

N = f / D Dimensionless ratio
Focus & Depth of Field

Face Detection

A system that identifies human faces in the frame and prioritises them for focus and often for exposure.

Sensors & Digital Capture

False Colour

Coloured artefacts appearing on fine detail, caused by the colour filter array sampling different colours at different positions.

Genres, Movements & Theory

Farm Security Administration

A United States government programme of the 1930s and 40s that commissioned photographers to document rural poverty during the Depression.

Genres, Movements & Theory

Fashion Photography

Photography made to present clothing and to construct a mood or identity around it.

Lighting & Flash

Feathering

Aiming a light so the subject is lit by the softer edge of its beam rather than its centre.

Film, Darkroom & Historic Processes

Fibre-based Paper

Photographic paper whose emulsion is coated directly onto a paper base with no plastic layer.

g/m²
Cameras, Formats & Systems

Field Camera

A folding large-format camera built light enough to carry, trading some movement range for portability.

Optics, Lenses & Filters

Field Curvature

A defect in which a lens focuses a flat subject onto a curved surface rather than the flat plane of the sensor.

Composition & Visual Design

Figure-Ground Relationship

The perceptual separation of a subject from its background, which determines whether it reads clearly.

Files, Metadata & Workflow

File Naming Convention

A consistent rule for naming image files so they sort predictably and stay unique.
