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 1.5-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:
AWHITE OK: 3700K
AWHITE: running
AWHITE: window
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 to Auto and 90% and the knee is
turned off.
