Colour Bar

Optical filter selection

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)

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.

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.
