    4. Set your camera’s ISO to 100, or use ISO/ASA 100 film. Make sure your subject is within the VS-210’s automatic mode range, 5 meters (16 feet) at f/4.0 and 10 meters (33 feet) at f/2.0. Press your camera’s shutter-release button to take the picture. The Auto OK light will glow green momentarily to indicate that the proper exposure was attained.

  • Page 19: Bouncing Your Flash

    Remember that the shutter speed setting will only affect the background. Using a slower shutter will make the background behind your subject brighter and increase background or motion blur, while a faster shutter will keep the background sharp but make it appear darker if it is beyond the flash range. Note: Do not set the shutter speed faster than your camera’s maximum sync speed, or black bars might appear in your images.
  • Page 20 The VS-210 flash head can be tilted up at 45-, 60-, 75-, and 90-degree angles to the lens. When bouncing your flash, you may need to adjust your exposure settings, since the level of light falling on your subject will be reduced.
