   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

4. Sunny 16 rule - Wikipedia

   en.wikipedia.org/wiki/Sunny_16_rule

   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 ...

6. Exposure value - Wikipedia

   en.wikipedia.org/wiki/Exposure_value

   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 ...
