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 flash brightness of the external flash by
adjusting the brightness control knob
located on the backside of the flash head. Take some test pictures
and experiment with the effect of the brightness control.
If the test image is over exposed (white or washed out colors),
turn the power adjustment 1 or 2 bars clockwise to reduce the
flash brightness and take another picture. Do this until the image
exposure satisfactory.
If the test image is under exposed (dark), turn the power
adjustment 1 or 2 bars 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 counter clockwise,
to the “A” position, the flash will be set to Auto mode, and
automatically adjust the flash brightness.
