Taking Pictures : The Details-Using the Camera Controls (User Sets 1, 2, 3) Reacting Faster to Light: Sensitivity (ISO Equivalency) What Is "Sensitivity"? "Sensitivity" is a measure of how quickly your camera reacts to light. The higher the sensitivity, the less light needed to make an exposure, allowing the same exposure to be achieved with higher shutter speeds or smaller apertures. In a digital camera, increased sensitivity is similar to using a fast film: higher sensitivities allow higher shutter speeds, at the expense of mottling, or "noise" (the digital equivalent of film "grain") appearing in the final image. Adjusting Sensitivity In User Set A, the camera sets sensitivity automatically in response to lighting conditions. In User Set 1, 2, or 3, you can choose a fixed value for sensitivity from four possible settings. Sensitivity is set by rotating the command dial while pressing the ISO ( ) button. The sensitivity setting cycles as follows: AUTO, 800, 400, 200, and 100. Sensitivity is displayed in control panel and monitor or viewfinder. After ISO button is released, ISO icon appears in control panel when sensitivity is above 100. At setting of AUTO, AUTO is displayed in monitor or viewfinder until ISO button is released; ISO icon then appears whenever sensitivity is above 100. + Press while rotating command dial Noise At shutter speeds of 1/30 s or slower, mottling ("noise") may appear in the final picture. We recommend that you either choose a faster shutter speed or turn Noise Reduction on ( 117). 78
