Degree of exposure to some source of risk.
Expression of the nature of a photographic emulsion's response to light. Can be concerned with degree of sensitivity as expressed by film speed or response to light of various colours (spectral sensitivity).
(physiology) responsiveness to external stimuli; "sensitivity to pain"
The degree to which a person is affected by external stimuli.
Degree of responsiveness of a film to light.
The degree to which an organism is affected by a drug. See also Resistance.
The degree to which a photographic emulsion reacts to light. Fast film, for example, has greater sensitivity than slow film.
With traditional film cameras, sensitivity, also known as ISO, represents the film's sensitivity to light. A lower ISO number means that the film needs more light to take a picture than does film with a higher ISO. Because digital cameras do not use film, manufacturers have had to create "sensitivity" settings. Some digital cameras only operate at one sensitivity level — others offer sensitivity settings of 100, 200 and 400, to mimic the effects of using film with a speed of 100, 200 or 400. These settings can be very useful; however, because they are achieved artificially, in some cameras they can result in slightly increased noise and color saturation.
Sensitivity means the degree to which photographic emulsion reacts to a light source. Fast film such as ISO 1600 has greater sensitivity than slow film such as ISO 100.
