Shooting 3 Shoot the image. The correct exposure has been set if the shutter speed and aperture value show in white. • If the shutter speed shows in red on the LCD monitor, the image is under exposed (insufficient light) or overexposed (too much light). Adjust the aperture value using the left and right buttons until the shutter speed display turns white. • Some aperture values may not be available with certain zoom positions. • For functions available in this mode, see page 224. • Please note that camera shake becomes a factor at low shutter speeds. If the camera shake warning appears in the LCD monitor, secure the camera to a tripod before shooting. • In this mode, the shutter speed range with synchronized flash is 1/60 second to 1/500 second. The aperture value setting may therefore be changed automatically to match the synchronized flash speed even if its value was set previously. Aperture Value Display The larger the aperture value, the smaller the lens aperture.
