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.
Underwater recording
Attachable to the left
and right shoes
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 characteristics underwater
Water absorbs light, especially red light, so that objects in
deep water are seen as bluish. The color of objects is affected
by the clarity of the water.
Best time for recording
The best recording time is from 10:00 a.m. to 2:00 p.m.
When the sun 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 wide-
conversion lens (not supplied) is recommended.
Camera work In slow and stable motion
When recording, keep your body stable.
An unstable shot will be magnified on the TV screen. Move
the video camera recording as slowly as possible. As most
of the object underwater move, you can record a good
programme without moving the video camera recorder.
