5.6 Color temperature

For true color reproduction the ambient lighting conditions must be compensated for by
selecting a value for the color temperature. The standard file setting is 3200 K (normally used
for tungsten and indoor lighting). Two other reference color temperatures are available: 5600 K
(for outdoors, clouded conditions) and 7500 K (for outdoors, clear blue skies).
The memory positions (FL50, FL60, AW1 and AW2) are available to store the results of the
auto-white measurement process. The memory positions store measured values using the
automatic white balance switch at the front. The FL positions are recommended for shooting
with fluorescent light.
A continuous automatic white balance position (AWC) is also available. This function
continuously measures the white balance and adjusts accordingly. It can be used when a
constant color balance is required under changing lighting temperatures (sunsets, indoors/
outdoors use).
In the auto-white positions an electronic color filter can be adjusted in the VIDEO menu. This
varies the color balance to obtain warmer or colder color effects. When an automatic white
balance process is performed, the electronic color filter is reset to its default value.
