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
required, and halogen lamps provide the most
natural artificial light while maintaining a constant
color 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 camcorder 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:
• 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.
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
problem by manually setting the gain (see
page 26).
