Optical filter selection
A neutral density filter and a special effect filter can be placed
in the path of the optical signal to modify the incoming light.
The filters are selected via the filter switches at the top-front
of the camera. These filters can be used, for example, to
control depth of field.
The camera does not need colour optical filters to be able to
white balance correctly. The range of the auto-white balance
is so wide (from 2.5K to 20K) that there is never any need to
use colour filters to obtain the correct white.
Colour Bar
The left side panel also contains a button for switching on the
colour bar test signal. The colour bar is a standard test signal
which is used to set up and check the camera before use.
When the colour bar is selected the following functions are
temporarily set to the values listed below:
Black stretch
:
Off
White limiter
:
Off
Zebra

Safe area (VF)

Cadre (VF)

Gain selection
Depending on the available light levels it may be necessary
to adjust the gain of the camera. The gain is selected via the
Gain up/down switch on the left side panel. When this switch
is pressed initially, the current value of the gain in dB is
displayed in the viewfinder.
A new value is chosen by scrolling up or down through the five
preset values (-, 0, +, ++ and +++). The actual dB value of
these gain steps can be set in the install menu.
The -, + and ++ indicators at the top of the 2-inch viewfinder
show which preset is selected.
