An ambiguous abbreviation that should be avoided. Some writers use it to mean lateral (transverse) chromatic aberration, TCA, while others use it to mean longitudinal (axial) chromatic aberration, LoCA. LCD: Liquid crystal display. A technology often used in the monitor screens of digital cameras, etc. [4] [11] LED: Light-emitting diode ...
ISO arithmetic speeds from 4 to 3200 are taken from ISO 5800:1987 (Table "ISO speed scales", p. 4). ISO arithmetic speeds from 6 to 10000 are taken from ISO 12232:1998 (Table 1, p. 9). ISO 12232:1998 does not specify speeds greater than 10000.
For photographic film, sensitivity is referred to as film speed and is measured on a scale published by the International Organization for Standardization (ISO). Faster film, that is, film with a higher ISO rating, requires less exposure to make a readable image. Digital cameras usually have variable ISO settings that provide additional ...
In digital photography, exposing to the right (ETTR) is the technique of adjusting the exposure of an image as high as possible at base ISO (without causing unwanted saturation) to collect the maximum amount of light and thus get the optimum performance out of the digital image sensor.

An example of the use of f-numbers in photography is the sunny 16 rule: an approximately correct exposure will be obtained on a sunny day by using an aperture of f /16 and the shutter speed closest to the reciprocal of the ISO speed of the film; for example, using ISO 200 film, an aperture of f /16 and a shutter speed of 1 ⁄ 200 second. The f ...
The CAS code shows this is (top row) ISO 125 film, (bottom row) 24 exposures, +3/−1 f-stop exposure tolerance. The DX barcode reads 017563, showing DX number 109-12, 24 exposures. DX ( D igital inde X ) encoding is a standard for marking 35 mm and APS photographic film and film cartridges, originally introduced by Kodak in 1983.

It is based upon, and compatible with, the ISO standard raw image format ISO 12234-2, TIFF/EP, and is being used by ISO in their revision of that standard. [28] Makers of "niche" cameras who might otherwise have difficulty getting support from software companies frequently use DNG as their native raw image format.
