SUPPLEMENTAL INFORMATION
What is “colour temperature’?
Light is composed of various colour components
in different proportions. A relationship exists
between the temperature of a light source and
the colour components of the emitted light; as
the temperature rises, the colour of the light
varies from red, orange, yellow, white to blue
in that order. ‘Colour temperature” is a value
that expresses differences in colour among light
sources, measured in Kelvin degrees. Bluish
light has a higher colour temperature than red-
dish light.
What is “white balance’’?
Making the colours look natural on TV is what
white balance is all about. Because a camera is
not as adaptable as the human eye, if a light
source is reddish, white subjects in that light are
recorded as reddish. White balance adjustment
is performed to compensate for colour tem-
perature variations of light so that whites are
reproduced as white. Correct white balance
makes all other colours correct. The GR-65E
can perform automatic white balance adjust-
ment in the full-auto mode. However, if illumi-
nation is insufficient, white balance adjustment
cannot be performed. To obtain correct colours,
therefore, sufficient i!lumination is essential.
What is “illuminance”?
“Iltuminance’' (also called ’'luminance’’) is the
intensity or brightness of light, expressed in
lux. The GR-65E is designed to provide best
pictures under the conditions of a 700-lux
illuminance, although shooting is possible all
the way down to 10 lux. To obtain good
pictures in very bright fight, the use of an ND
{neutral density) filter is recommended. (See
chart on this page.)
How to get good colour pictures
The simplest way is to provide sufficient light-
ing (close to the camera’s reference illuminance}
and accurately adjust the camera to the colour
temperature of that lighting. If light sources of
different colour temperatures are used together,
accurate white balance adjustment is very dif-
ficult. For example, if natural light is mixed
with artificial light, which is likely to- occur
next to windows, correct colours of the subject
are difficult to obtain. It is recommended in
such cases that curtains in the room be closed
to shut out light from outside. Also, when
artificial lighting devices are used, they should
all have the same colour temperature. For ex-
ample, it is recommended that incandescent or
halogen jamps not be used together with fluores-
cent lighting.
