VIII. External Flash adjustments
Now that you are familiar with camera
adjustments that effect picture color and
brightness, this section will describe how to
adjust the external flash.
Flash Brightness control
You can manually or automatically control
the external flash brightness by adjusting the
brightness control dial located on the back of the flash head. 10
is the brightest setting. Take some test pictures and experiment
with the effect of the brightness control.
If the test image is o
ver-exposed (white or washed out colors),
turn the power adjustment 1 or 2 steps clockwise to reduce the
flash brightness and take another picture. Do this until the image
exposure is satisfactory.
If the test image is under exposed (dark)
, turn the power
adjustment 1 or 2 steps counter-clockwise to increase the flash
brightness and take another picture. Do this until the image
exposure is satisfactory.
Remember that the flash will only reach about 6 ft to 8ft (1.8m to
2.4m) depending on water visibility, so make sure to keep your
underwater shooting distance within that range.
If you turn the brightness control all the way clockwise, to AUTO,
the flash will automatically adjust the brightness.
