The automatic white balance process is performed independent of the Color Filter. The Color
Filter is not disabled when AWC is on.
4.8.4 Selecting color temperature
The up/down color temperature switch on the left side of the camera allows a choice
between three preset color temperatures:
• 3200 K - for indoor lighting conditions
• 5600 K - for outdoors, clouded conditions
• 7500 K - for outdoors, clear blue skies
and four memory positions:
• FL50 - memory position for 50 Hz fluorescent light (matrix is set to CoolFL and exposure
to 50 Hz )
• FL60 - memory position for 60 Hz fluorescent light (matrix is set to CoolFL and exposure
to 60 Hz )

If AWC is selected, the non-standard indicator in the viewfinder lights (only for ocular
viewfinders).
When the switch is first pressed, the viewfinder displays the current value. Select a new value
by scrolling up or down through the available values.
The viewfinder also displays the actual value of a measured color temperature. The range of
the auto-white balance is from 2500 K to 20000 K.
4.8.5 Variable color temperature
The color temperature switch on the left-front side of the camera can also be used to vary the
color temperature continuously between its minimum and maximum value (2500 K to
20000 K).
1. Hold the switch continuously in the up or down position until you see the value in the
viewfinder change.
2. Release the switch when you reach the value you want. This exits the value selection
mode.
3. Using the switch momentarily again sets the color temperature to the nearest standard
value.
