XI. Great pictures made easy

There are plenty of challenges that photographers face in the

underwater world. Please take some time to review SeaLife’s

online guide called

Great Pictures Made Easy

by visiting

www

.sealife-cameras.com. The guide is located under the

Technical Support menu.

The following information summarizes the basic principles of

underwater photography.

1. Crystal clear water

Clear water is essential for good underwater pictures. Fine

particles suspended in the water, like algae and sediments,

cause low visibility and small spots to appear in your picture,

commonly referred to as “backscatter”. Your external flash

will help you reduce the backscatter effect because the flash

only illuminates the outer rim of the floating debris. As a

general rule, limit your shooting distance to 1/10 of the water

visibility.

2. Limit your shooting distance to 6 ft (1.8m)

Water is 800 times denser than air and quickly absorbs light.

Your external flash has a limited reach of 6ft (1.8m) to 8ft

(2.4m) depending on water visibility. Keep your shooting

distance inside of 6 ft (1.8m). 4 ft (1.2m) is ideal. Consider the

SeaLife Wide Angle Lens accessory which allows to keep a

closer shooting distance and fit everything into the picture.
