Video recording takes place under various light sources, from
sunlight as the main natural light source to a wide range of
artificial light sources such as fluorescent lamps. As each of
these light sources has a different colour temperature, each of
them gives the colours of the subject a slightly different tint.
Human eyes can easily adjust to different kinds of lighting and
recognize an object as having the same colour, even under
different light sources.
The eye of the Movie Camera (lens), however, cannot adapt
to the change in lighting and is influenced by the lighting.
Therefore, depending on the light source, the picture would be
recorded with a bluish or reddish tint. To minimize the
influence of the lighting on the colours of the subject, an
adjustment called White Balance Adjustment is necessary.

∫

This Movie Camera offers both Auto White Balance
Adjustment and Manual White Balance Adjustment. When the
Movie Camera is in the Full Auto Mode, the internal system of
the Movie Camera automatically determines the temperature
of the light and compensates the tint of the subject
accordingly. White is the basic colour by which the tint is
determined. Because this adjustment is performed based on
the white colour, it is called White Balance Adjustment. The
optimum settings for several light sources are stored in the
memory of the Movie Camera. The internal microcomputer
compares the colour temperature of the light received by the
White Balance Sensor positioned on the front of the Movie
Camera with the colour stored in memory, and selects the
setting for the most similar tint.
Be careful not to cover the White Balance Sensor (

l 12) with

your hand, etc.

∫

Although this Movie Camera stores the optimum settings for
several light sources in memory to correctly judge the white
colour, it cannot cope with all light sources. Therefore, to
record under those types of lighting (

l 90, 92) which cannot

be correctly adjusted with Auto White Balance Adjustment,
use Manual White Balance Adjustment. (

If you look at an object through a magnifying glass and move
it closer or further away from your eye, you will reach a point
where the object becomes clearly visible. Being focused or in
focus means that the subject can be seen with optimum
clarity and sharpness. The distance between the lens and the
point where the rays of light come together is called Focal
Distance or Focal Length and depends on the size and shape
of the lens.
Human eyes have lenses too, and when we look at objects at
different distances, the shape of these lenses changes
automatically so that we can always see the objects clearly.

∫

The image of the subject enters the Movie Camera through
the lens and is converted into an electrical signal (video
signal) for recording onto tape. Based on this signal, the Auto
Focus System automatically adjusts the focal distance by
moving the focusing lens forward or backward.
The focus is adjusted on the subject in the centre of the
Finder.
