Correct white balance adjustment is important for an exact color reproduction!
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
(#16)
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 19). If you work with negative transparencies and a
lightbox, 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, slide box and external lightbox (no
light).
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 the Visualizer's light and an external lightbox (bottom light) or if the room light is turning
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 (e.g. a sheet of paper) until there is only white on the screen and press the
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 lightbox, zoom to the smallest picture size until there is only white on the screen and press the
for 2 seconds.
Lightbox with x-rays:
Turn off the light of the Visualizer with the LIGHT key and switch on the lightbox. Place an x-ray on the
lightbox, zoom out until the whole x-ray is picked up and press the
for 2 seconds.
Please note: False colors can also be caused by incorrect color settings on a connected projector or
monitor. It is recommended to adjust the white balance of the Visualizer at first and if the results are still not
satisfactory, the monitor or projector should be checked.
This means that the white balance
is continuously adjusted automatically.
