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 blue content. This phenomenon, known as " Selective Light Absorption ," increases as you go deeper underwater 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, colorful photograph .
Taking photographs highlighting the blue of the sea . . .
Try to shoot at an upward angle to allow the background ambient light to enter into the picture.
In TIL 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 colors by the light from the Speedlight.
