WolfVision VZ-8plus 4 User Manual - Handbuch (Seite 11)

Correct white balance adjustment is important for exact color reproduction!
This means that the white balance
is continuously adjusted automatically.
For an exact white balance, at least 10% of the recorded image should be white.
For a precise fixed white balance adjustment use the "One Push" white balance. This can be done by
pressing the LIGHT key (#4) 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).

For specialists: The Visualizer can be switched between "Auto Tracking", "One Push" and "Manual"
white balance mode in the on-screen menu (see page 16). 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!
Each time the lighting condition changes, the Visualizer's camera must readjust its white balance, in order
to optimize the color reproduction. The lighting conditions (color temperature) change, for example, if
changing between the Visualizer's light and an external lightbox (bottom light) or if the room light is switched
on or off.
The standard setting of the Visualizer is "Auto Tracking" white balance.
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 a 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 and press the
for 2 seconds.
Lightbox with transparencies (optional):
Turn off the light of the Visualizer and switch on the optional lightbox. Remove everything from the light
box, zoom to the smallest picture size until there is only white on the screen and press the
for 2
seconds.
Lightbox with x-rays (optional):
Turn off the light of the Visualizer and switch on the optional lightbox. Place an x-ray on the light box,
zoom out until the whole x-ray is picked up and press the
for 2 seconds.
Please note: False colors can also be due to incorrect color settings of your projector or monitor. It is
recommended to adjust the white balance of the Visualizer first and if the results are still not satisfactory,
then the monitor or projector should be checked.
