Setting ISO Sensitivity The ISO sensitivity setting determines the camera's sensitivity to available light. As ISO sensitivity is increased, less light is required to expose an image, which permits faster shutter speeds. This is helpful for shooting fast moving subjects without blurring, but it also amplifies any digital noises caught in an image, which can produce a picture with a grainy appearance. To set ISO sensitivity, pull up and rotate the outer ring of the shutter speed dial to select 200, 400, 800, or 1600. Setting the Exposure 2 You can set the exposure automatically or manually. Automatic exposure is a convenient feature that works sufficiently under most conditions. With manual exposure, you have more control over how 2 your pictures will be exposed. Setting the Shutter Speed Automatically 2 Use the aperture priority automatic exposure (AE) feature to automatically set the shutter speed for the selected aperture setting. This is useful when you want to control the depth of field or to produce special effects, or when you simply want to take point-and-shoot 2 snapshots. The AE feature works sufficiently most of the time, but under certain 2 conditions you can also apply exposure compensation within the range of +2 EV to -2 EV in 1/3 EV increments. You may, for example, increase 2 the compensation value by one notch (+1/3 EV) to overexpose a subject standing in a bright background. Likewise, if your subject is too bright for the background, you would lower the EV to underexpose the subject. 2 2 2 2 Taking Photos 21
