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 assigned PRESET key 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 13). 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.

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 (optional bottom light) or if the room light is

turning on or off.

The standard setting of the Visualizer is "Auto Tracking" white balance.

(LIGHT)

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 (and room light):

Zoom in on a white object (e.g. a sheet of paper) until there is only white on the screen and press the

assigned PRESET key (LIGHT) for 2 seconds.

Optional Lightbox with transparencies:

Turn off the light of the Visualizer with the assigned PRESET key and switch on the lightbox. Remove

everything from the light box, zoom to the smallest picture size until there is only white on the screen and

press the assigned PRESET key (LIGHT) for 2 seconds.

Optional Lightbox with x-rays:

Turn off the light of the Visualizer and switch on the lightbox. Place an x-ray on the light box, zoom out

until the whole x-ray is picked up and press the assigned PRESET key (LIGHT) 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,

the monitor or projector should be checked.

This means that the white balance

is continuously adjusted automatically.

White Balance Adjustment

IMPORTANT

Lightbox (optional)

When a lightbox is used, the top light of the Visualizer should be switched off with the assigned PRESET

key (LIGHT). Using a bottom light has the disadvantage that the Synchronized Lightfield of the top light no

longer marks the pick-up area of the built-in cameras.

The recommended lightbox for the Ceiling Visualizer is the WolfVision Lightbox LB-38.
