Basic Tips on Underwater Flash Photography

The basic aspects of underwater flash photography will be

reviewed in this section.

The Role of the Speedlight...

The primary purpose of the Speedlight underwater is to accurately reproduce

the subject’s colors. At a depth of three meters (10 feet), the red content of the

subject will begin to be absorbed by the water, resulting in a photograph strong

in biue content. This phenomenon, known as “Selective Light Absorption,’’

increases as you go deeper undenvater and move farther from the subject.

Using a Speedlight effectively will restore the lost color to your photographs

and create better contrast.

Try to stay as close as possible to your subject to reduce the amount of water

between your camera and subject. This will result in a sharp, colorfui

photograph.

Taking photographs highlighting the blue of the sea...

Try to shoot at an upward angle to allow the background ambient iight to enter

into the picture.

In TTL flash mode, select the aperture value to get the correct exposure while

aiming the camera at the blue background. Then set the aperture dial.

In this condition, you can take photographs with correct exposure and a natural

blue background. The main subject can be reproduced in vivid coiors by the

light from the Speedlight.

—In manual flash mode, select the combination of shutter speed and aperture value to

obtain the correct exposure against the background.
