RCA ProV712 / PRO 8 Camcorder
(160-0867)                 Lighting                   Faxback Doc. # 34799

500 to 100,000 lux of light is best for clear good-quality recordings.
Though recording is possible with less light, insufficient lighting can
result in poor picture quality.

Reference

Lighting is not only one of the most important areas in producing home
videos, but also one of the most overlooked.  Good lighting can often mean
the difference between a great picture and a poor one.  Lighting is also
essential for correct white balance.

In most outdoor, day time scenes, natural lighting is adequate for home
videos.  Indoors, the situation becomes more complicated.  Artificial
lighting is required, and halogen lamps provide the most natural artificial
light while maintaining a constant color temperature over a long period.

Good lighting is difficult to achieve.  There are many problems waiting to
catch the unwary.  Simply mounting one light or several lights on either
side of the Camcorder will only make your subject look flat and two-dimen-
sional.  To make a subject more interesting, use lighting to model your
subject and to add or create emphasis in a scene.

NOTES:  The figures in the charts are approximations.

        The auto white balance operates automatically within the range of
        "AUTO" shown in the chart.  However, it will satisfactorily operate
        from 2,500 K up to 8,000 K, although the picture may take on a red
        or blue tint.
