LIGHTING
For clear good-quality pictures you will need between 500 and 100,000 lux
you can record in less light, however
the picture quality may suffer. Adequate lighting is also essential for correct white balance.

Video Lighting
Lighting is one of the most important areas in
home videos. Also one of the most overlooked.
Good lighting can often mean the difference bet-
ween a great picture and a poor quality one. And
lighting is essential for correct white balance.
In most outdoor situations natural lighting is
adequate for home videos. Indoors the situation
becomes more complicated. Artificial lighting is re-
quired and tungsten (or quartz) lamps provide the
most natural of artificial light
sources, while provid-
ing a constant colour temperature over a long life.

Good lighting is difficult to achieve-and there are
many problems to catch the unwary. Simply
mounting one light on or several lights 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.
