There are several variants: sRGB, ISO RGB and some proprietary standards. Used mainly in colour displays: computer monitors, digital cameras, etc. [9] RP: Resolving power. Usual meaning is the reciprocal of the distance between two just-distinguishable subject details. [7] S or TV: Shutter priority or time value.

For example, as of 2008, Nikon cameras allow one to set the maximum and minimum ISO sensitivities, and slowest shutter speed that will be used in automatic modes, [4] while Canon cameras will select within the fixed range of ISO 400–ISO 800 in Auto ISO mode. In Nikon cameras, the Auto ISO mode first adjusts the shutter speed, keeping ISO at ...
To photograph outdoor night sports with an ISO 400–speed imaging medium, search Table 2 for "Night sports" (which has an EV of 9 for ISO 100), and add 2 to get EV 400 = 11. For lower ISO speed, decrease the exposure values (increase the exposures) by the number of exposure steps by which the speed is less than ISO 100.
In photography, shutter speed or exposure time is the length of time that the film or digital sensor inside the camera is exposed to light (that is, when the camera's shutter is open) when taking a photograph. [1] The amount of light that reaches the film or image sensor is proportional to the exposure time.
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 ...

ISO settings like 102,400 can yield guide numbers in excess of 1220 (m) / 4000 (ft) that seldom if ever permit extremely long-range flash photography due to particulates and aerosols typically present in outside air that fog images with haze glare and attenuate the reach of the light. Except in unusual atmospheric conditions, extraordinarily ...
