White Balance Adjustment - WolfVision VZ-C32 Bedienungsanleitung

White Balance Adjustment

Correct white balance adjustment is important for an exact color reproduction!
Each time the lighting condition changes, the Visualizer's camera must readjust its white
balance, in order to optimize the color reproduction. The lighting condition (color
temperature) changes, for example, if changing between Visualizer's light and an external
lightbox (bottom light) or if room light is turning on or off.
The standard settings of the Visualizer are the following:
When the Visualizer's light is switched on: fixed white balance.
When the Visualizer's light is switched off: "auto-tracking" white balance.
the white balance is continuously adjusted automatically.
For an exact white balance, at least 10% of the recorded image should be white
(measurement area is the center of the image).
For a precise fixed white balance adjustment use the "One Push" white balance. This can
be done by pressing the LIGHT key (#33) for 2 seconds. When the white balance is stored
an on-screen message appears. Setting a "One Push" white balance switches off the "Auto
Tracking" mode (When the unit is switched off and on again the "Auto Tracking" mode will
be reactivated).
Normally there is no need for a manual white balance adjustment. However, if the colors on
the screen still appear to be wrong, the white balance can be adjusted manually (one-push):
Hints to perform an One-Push white balance:
Top light: Zoom in on a white object (i.e. a sheet of paper) until there is only white on the
screen, press the LIGHT key for 2 seconds.
Lightbox with transparencies: Turn off the light of the Visualizer with the LIGHT key and
switch on the lightbox. Remove everything from the light box and zoom to the smallest
picture size until there is only white on the screen, press the LIGHT key for 2 seconds.
Lightbox with x-rays: Turn off the light of the Visualizer and switch on the lightbox. Place
an x-ray on the light box and zoom out until the whole x-ray is picked up, press the LIGHT
key for 2 seconds.
Please note: False colors can also be due to wrong color settings of your projector or
monitor. It is recommended to adjust the white balance of the Visualizer at first and if the
results are still not satisfactory, monitor or projector should be checked.
For specialists: The Visualizer can be switched between "Auto Tracking", "One Push" and "Manual"
white balance mode in the on-screen menu (see page 15). If you work with negative transparencies
and a light box, use a blank (black in the image) part of the negative film for white balance adjustment!
The "one Push" white balance will be separately adjusted and stored for top light and external light.
