Shooting - Selecting Particular Effects z The nature of CCD image sensors is such that noise in the recorded image increases at slow shutter speeds. This camera, however, applies special processing to images shot at shutter speeds slower than 1.3 seconds to eliminate the noise, thereby producing high-quality images. Nevertheless, a certain amount of processing time may be required before the next image can be shot. z See page 206 for settings that can be changed in this mode. z Please note that camera shake becomes a factor at slow shutter speeds. If the camera shake warning appears on the LCD monitor, secure the camera to a tripod before shooting. z The fastest shutter speed that can be used effectively with the flash is 1/250 second. If you try to select a speed faster than 1/250 second, the camera automatically resets the shutter speed to 1/250 second. z The aperture value and shutter speed change according to the zoom state as follows. Wide Angle Telephoto Aperture Value F2.0 - 3.5 F4.0 - 8.0 F3.0 - 5.0 F5.6 - 8.0 Shutter Speed (seconds) to 1/1250 to 1/2000 to 1/1250 to 1/2000 83
