For their contribution to digital photography, Boyle and Smith were awarded the Nobel Prize for Physics in 2009. [2] In 1973, Fairchild developed a 100 x 100 pixel interline CCD image sensor. [3] This CCD was used in the first commercial CCD camera, the Fairchild MV-100, which was introduced in late 1973.
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.
Digital cameras usually have variable ISO settings that provide additional flexibility. Exposure is a combination of the length of time and the illuminance at the photosensitive material. Exposure time is controlled in a camera by shutter speed , and the illuminance depends on the lens aperture and the scene luminance .
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
