Camera Recording
Lighting
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, daytime 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
colour 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 VIEWCAM will only make
your subject
look flat
and two-dimensional. To make a subject more
interesting, use lighting to model your subject and to
add or create emphasis in a scene.

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.
