Outdoor photographers use fill flash to remove shadows.
Even when you are shooting outdoors, you may need to use fill flash to remove shadows or brighten certain parts of an image to compensate for sub-optimal lighting conditions. Fill flash should normally be one or two f/stops under the nominal exposure for your subject. Set your shutter speed at 1/250 or less to sync with the flash unit and use aperture to adjust exposure if you are using manual modes.
Instructions
External Slave Unit
1. Use an off-camera flash unit for greatest flexibility. Nikon SB-600 and SB-800 units have built-in compatibility with the Nikon D200.
2. Turn on both the flash unit and the camera. Select matrix or center-weighted metering mode on the camera.
3. Go to the "Pencil" menu on the camera and select "Flash." Next, select the "Built-in Flash" option and then "Commander Mode."
4. Select the "CSM" menu on your flash unit. Press "-" or "+" to bring up the wireless communication icon and then press "Mode" to turn on wireless communications.
5. Use the flash compensation menu on the camera to adjust the intensity of the flash unit.
