Sensitivity P, S, A, and M Modes Only Sensitivity (ISO equivalency) is the digital equivalent of film speed. The higher the sensitivity, the less light needed to make an exposure, allowing higher shutter speeds and smaller apertures. Much as film with a high ISO rating tends to produce "grainy" images, high sensitivities may be associated with "noise"-randomly spaced, brightly colored pixels concentrated in dark parts of the image. Noise reduction ( 109) can be used to reduce noise in pictures taken at shutter speeds of slower than ¼ s. In (auto) and scene modes, the camera automatically raises sensitivity when lighting is poor. In P, S, A, and M modes, the following options are available: Option Description Approximately equivalent to ISO 50. Recommended unless lighting is poor or 50 faster shutter speeds are required (e.g., when subject is moving). Noise may appear in pictures taken at settings above this value. 100 Approximately equivalent to ISO 100. 200 Approximately equivalent to ISO 200. 400 Approximately equivalent to ISO 400. Approximately equivalent to ISO 50 under normal conditions; when lighting Auto is poor, however, camera automatically compensates by raising sensitivity to maximum of ISO 200 equivalent). ISO icon appears in control panel and shoot- ing display when sensitivity is raised.
