Underwater Recording - Sony MPK-TRV7 Operating Instructions Manual

Underwater recording

Recording underwater is different from recording on land because it is affect by the
clarity, depth of the water and the light condition. The following are hints for good
recording underwater.
Colour characteristic underwater
Water absorbs light, especially red light, so that objects in deep water are seen bluish.
The colour of objects is affected by the clarity of the water.
To record in natural colour, use a colour filter (not supplied).
VCL-MK1*
VF-MK11*
VF-MK12*
* These accessories are included in
the accessory kit ACC-MK1.
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 camcorder as
well as human eye. Using a wide-conversion lens (not supplied) is recommended.
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 camcorder as slow as
possible. As most of the object underwater move, you can record a good program
without moving the camcorder.
