Useful Features for Camera Recording
Lighting
For clear, good-quality recording, 500 to 100,000
lux is needed Recording is also possible with less
light, but the picture quality may suffer. Adequate
lighting is also essential for correct white balance

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 re-
quired, and halogen lamps provide the most
natural artificial light while maintaining a constant
colour temperature over a long operating life.
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 the lighting to model your subject
and to add or create emphasis in a scene.

Notes:
l The figures in the charts are approximations.
l 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.
Lighting indicator (“LIGHT”)
When the “LIGHT” indicator appears on the moni-
tor, it means that there is not enough illumination
for recording. Either move to a brighter location or
increase the light. You can also correct the prob-
lem by manually setting the gain (see page 32).
