Underwater recording
Recording underwater is different from recording on land because it is affected by the clarity and depth of the water and the light conditions. The following are hints for good recording underwater.
Color characteristic underwater
Water absorbs light, especially red light, so that objects in deep water or in the distance are seen as bluish. The color of objects is affected by the clarity of the water.
To record the subject with nearly actual color, use the color filter.

Best time for recording
The best recording time is about from 10:00 a.m. to 2:00 p.m. When the sun is its highest, optimum results can be obtained.
Subject size underwater
Since the refractive index underwater is higher than that in air, an object appears 1/4 more closer, and therefore larger. This phenomenon affects the lens on the video camera recorder as well as the human eye. Using a
Camera work on slow and stable motion
When recording, keep your body stable.
An unstable shot will be magnified on the TV screen. Move the video camera recorder as slowly as possible. As most of the object underwater move, you can record a good programme without moving the video camera recorder.
Underwater video light
In deep water or under rocks where direct sunlight does not reach, recording with an underwater video light is recommended.
To record at night, use a powerful underwater video light.
