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, 10% of the recorded image should be white (measurement
area is in the center of the image).
For a precisely fixed white balance adjustment use the "
One Push" white balance. This can
be done by completely zooming in on a white sheet of paper on the working surface and
pressing the LIGHT
key (#25) 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
When the lighting conditions change (e.g. light box, sunlight or different
room light) the white balance should be readjusted!
For specialists:
If you work with negative transparencies and a light box,
use a blank (black in the image) piece 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 box
.
" Auto Tracking" is the default white balance setting when the Visualizer is shipped.
"Auto Tracking" mode will
be reactivated).
The Visualizer can be switched between "Auto Tracking", "One Push" and "Manual" white
balance mode in the on-screen menu (see page 13)
