XV. 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
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 photos and videos.
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 SeaLife Wide Angle
Lenses which allow a closer shooting distance and fit everything
into the image.
