■ White Balance Adjustment
While most recording with a Movie Camera is probably done
outdoors under sunlight, video recording is also done very
often under artificial light sources, both indoors and outdoors.
However, each of these light sources gives the subject slightly
different colours.
Human Eyes
Human eyes can easily adjust to different kinds of lighting and
see an object with the same colours even under different
lighting.
Movie Camera
Unlike human eyes, the Movie Camera does not have the
innate ability to adapt to changes in lighting, and they influence
the colours being recorded. Therefore, depending on the light
source, the picture would be recorded with a bluish or reddish
tint. To minimise the influence of the lighting on the colours of
the subject, an adjustment called White Balance Adjustment is
necessary.
White Balance Adjustment
The White Balance Adjustment determines the colour of the
light and adjusts the colours so that white remains pure white.
As white is the basic colour of the entire colour spectrum, if
white is reproduced correctly, the other colours are correct and
natural, too.
Auto White Balance Adjustment
This Movie Camera stores the optimum settings for several
common light sources in memory. The Movie Camera judges
the recording situation by determining the tint of the light
received through the lens and by the White Balance Sensor
(-♦ 8), and it selects the setting for the most similar tint. This
function is called Auto White Balance Adjustment.
However, as the white balance settings for only a few light
sources are stored in memory, the white balance is not
correctly adjusted for other lighting conditions.
For the range of different types of lighting within which the
Auto White Balance Function can provide precise adjustment,
refer to the chart
{-*
100). For recording under lighting
conditions outside this range, the Auto White Balance Function
does not work correctly, and the recorded picture has a red or
blue cast. However, the same also applies, if the subject is lit
by more than one light source, even if these light sources are
within this range.
