5-4 Operator's Manual LDK 200 - Multi-role Digital Camera Head Shooting
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 LDK 200 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 : Off
Safe area (VF) : Off
Cadre (VF) : Off
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 1.5-inch
viewfinder show which preset is selected.
