With video cameras,
just as with films and photos, the color
temperature of light measured in Kelvin (K) must be considered in
order to attain color-true recordings. In the table (see page 79)
there are examples listed for some situations and light sources.
The adjustment necessary for attaining natural colors is called
WHITE BALANCE.
There are two possibilities for adjusting the S-VHS Movie to the
color temperature of the light (white balance):
—automatic white balance
—adjustment to fixed values and simultaneous use of filters.

Within the range of about 2500 K to 5500 K, the use

versa—is carried out during a scene.

filter recommendations for the named examples.
