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:

Approximately equivalent to ISO 50. Recommended unless lighting is poor or

50faster shutter speeds are required (e.g., when subject is moving). Noise may appear in pictures taken at settings above this value.

100Approximately equivalent to ISO 100.

200Approximately equivalent to ISO 200.

400Approximately 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-
