5.7.5 Colour temperature selection
For true colour reproduction the ambient lighting conditions must be compensated for by
selecting a value for the colour temperature. The standard file setting is 3200K (normally used
for tungsten light). Three other reference colour temperatures are available; 4700K (for
outdoors, clouded conditions), 5600K (for outdoors, clouded conditions) and 7500K (for
outdoors, clear blue skies).
The memory positions (FL, FL50, FL60, AW1 and AW2) are available to store the results of the
auto-white measurement process. The memory positions are filled with 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 colour balance is required under changing lighting temperatures (sunsets, indoors/
outdoors use).
In the auto-white positions an electronic colour filter can be adjusted in the
VIDEO
menu. This
varies the colour balance to obtain warmer or colder colour effects. When an automatic white
balance process is performed, the electronic colour filter is reset to its default value.
