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). Two other reference colour
temperatures are available; 5600K (for outdoors, clouded
conditions) and 7500K (for outdoors, clear blue skies).
Three similar memory positions (FL, AW1 and AW2) are
available to store the results of the auto-white measurement
process. The FL position is 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). When AWC is
selected none of the colour temperature indicators in the 2-
inch viewfinder light.
The colour temperature is selected via the up/down scroll
switch (White Bal.) at the left-front side of the camera. The
viewfinder displays the current value. A new value is chosen
by scrolling up or down through the available values.The
colour temperatures are shown in the following order:
White balance :
3200K
White balance :
5600K
White balance :
7500K
White balance :
FL
White balance :
AW1
White balance :
AW2
White balance :
AWC
The viewfinder displays the selected value and the actual
measured colour temperature. The range of the auto-white
balance is from 2.5K to 20K.
In the auto-white positions an electronic colour filter can be
adjusted in the system 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.

Auto-White Balance
If the reference colour temperatures do not match your
lighting conditions carry out the auto-white procedure as
follows:
a. Use the colour temperature switch to select one of the
memory positions FL, AW1 or AW2 in which to store the
measured colour temperature value.
b. Press once on the white balance switch at the front of the
camera to start the automatic white balance procedure.
The following appears in the viewfinder:
c. Point the camera so that the reference white surface is
between the two small white boxes.
d. Press the white balance button again to start the
measurement procedure. A message indicating that the
process is runnning appears.
e. When the process is completed (within a few seconds) the
OK message and the measured temperature appear in
the viewfinder.
The measured colour temperature is now stored in the
selected memory position and can be recalled as required.
The camera is now ready for use.
Note: During the auto-white measurement process iris is set
