Sunlit subject shot on a digital camera set to ISO 100, exposed at f/8 at 1/400 second which is the same exposure value as f/16 for 1/100 second, the recommended "sunny 16" exposure. In photography, the sunny 16 rule (also known as the sunny f /16 rule) is a method of estimating correct daylight exposures without a light meter. Apart from the ...

Illuminance is measured using a flat sensor; if the common value of C = 250 (unit: lux s ISO=lm s/m 2 ISO) is used, an EV of zero (e.g., an aperture of f /1 and a shutter time of 1 sec) for ISO = 100 corresponds to an illuminance of 2.5 lux (0.23 fc). At EV = 15 (the "sunny sixteen" amount of light) the illuminance is 82,000 lux (7600 fc). For ...

ISO: A system for quantifying the sensitivity ("speed") of a photographic emulsion, or a solid-state digital-camera's image sensor, to visible light. Normally followed by a numerical value, e.g.: ISO 100 or ISO 64/19°. Developed from the ASA and the DIN systems by the International Organization for Standardization. [4] JPEG
TAv: Some Pentax cameras such as Pentax K-50 has this mode for rapidly changing lights by using the widest aperture and the lowest ISO of continuously changing ISO between 1,000 and 3,200. [1] [2] The range of continuously changing ISO is dependent on the camera manufacture. Other manufacturers may provide this functionality through an ...
Common film speeds include ISO 25, 50, 64, 100, 160, 200, 400, 800 and 1600. Consumer print films are usually in the ISO 100 to ISO 800 range. Some films, like Kodak's Technical Pan, [30] are not ISO rated and therefore careful examination of the film's properties must be made by the photographer before exposure and development. ISO 25 film is ...
Areas of a photo where information is lost due to extreme darkness are described as "crushed blacks". Digital capture tends to be more tolerant of underexposure, allowing better recovery of shadow detail, than same-ISO negative print film. Crushed blacks cause loss of detail, but can be used for artistic effect.
