■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 may 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 image received through the lens and by the
White Balance Sensor («* 14), 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 several
light sources are stored in memory, the white balance is
not correctly adjusted for lighting conditions other than
those stored in memory.
For the range of different types of lighting within which
the Auto White Balance Function can provide precise
adjustment, refer to the chart above (■+ 152), 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 applies.it the subject is lit by more than one
light source, even if these light sources are within the
above range.
