s: Convey the Subject's Movement Shooting Tips To freeze the motion of a fast-moving subject Use a fast shutter speed such as 1/4000 sec. to 1/500 sec. To blur a running child or animal and convey an impression of motion Use a medium shutter speed such as 1/250 sec. to 1/30 sec. Follow the moving subject through the viewfinder and press the shutter button to take the picture. If you use a telephoto lens, hold it steady to prevent camera shake. To blur a flowing river or fountain Use a slow shutter speed of 1/30 sec. or slower. Use a tripod to prevent hand-held camera shake. Set the shutter speed so that the aperture display does not blink. If you press the shutter button halfway and change the shutter speed while the aperture is displayed, the aperture display will also change to maintain the same exposure (amount of light reaching the image sensor). If you exceed the adjustable aperture range, the aperture display will blink to indicate that the standard exposure cannot be obtained. If the exposure will be too dark, the maximum aperture (smallest number) will blink. If this happens, turn the dial to the left to set a slower shutter speed or increase the ISO speed. If the exposure will be too bright, the minimum aperture (highest number) will blink. If this happens, turn the dial to the right to set a faster shutter speed or decrease the ISO speed. D Using the Built-in Flash To obtain a correct flash exposure, the flash output will be set automatically (autoflash exposure) to match the automatically-set aperture. The shutter speed can be set from 1/200 sec. to 30 sec. 109
