Exposure & Metering

Dynamic Range

The span between the brightest and darkest tones a camera can record in a single frame while keeping usable detail at both ends.

DR = log₂(full-well / read noise) stops (EV)
Genres, Movements & Theory

Düsseldorf School

A group of German photographers taught by Bernd and Hilla Becher, known for large-format, systematic and often very large-scale work.

Genres, Movements & Theory

Editorial Photography

Photography made to accompany published text — articles, features and interviews — rather than to advertise.

Exposure & Metering

Effective Aperture

The working f-number of a lens once it is focused close, which is always darker than the marked aperture because the lens is extended away…

N_eff = N × (1 + m) f-stops (EV)
Sensors & Digital Capture

Effective Pixels

The number of photosites actually contributing to the final image, as distinct from the total on the chip.

Optics, Lenses & Filters

Entrance Pupil

The apparent size and position of the aperture as seen from in front of the lens, which is what the f-number is calculated from.

D = f / N mm

Environmental Portrait

A portrait made in a setting that tells the viewer something about the subject's life, work or identity.

Exposure & Metering

Equivalent Exposure

Any different combination of aperture, shutter speed and ISO that yields identical image brightness.

N₁²/t₁ = N₂²/t₂ stops (EV)
Cameras, Formats & Systems

Equivalent Focal Length

The full-frame focal length that would give the same angle of view as a given lens on a smaller format.

f_equiv = f × crop factor mm
