s: Action Shots Shooting Tips To freeze the action or moving subject. Use a fast shutter speed such as 1/4000 sec. to 1/500 sec. To blur a running child or animal giving the impression of fast movement. 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. How to blur a flowing river or water fountain. Use a slow shutter speed of 1/15 sec. or slower. Use a tripod to prevent camera shake. Set the shutter speed so that the aperture display does not blink in the viewfinder. 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 lowest aperture 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 highest aperture will blink. If this happens, turn the dial to the right to set a faster shutter speed or decrease the ISO speed. 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 flash sync speed can be set from 1/200 sec. to 30 sec. 77
