WolfVision VZ-C32 3 User Manual - Handbuch (Seite 9)

The working surface of the Visualizer (#3) has a special
crystalline white color, which is specially designed for perfect
reproduction of transparencies.
Even if you own an optional light box, it is recommended to use
the top light for transparencies due to the better color
reproduction and because the synchronized lightfield still shows
the pickup-area of the built-in camera.
The additional whiteboard foil can be used for direct annotation
with special whiteboard markers. WolfVision offers spare
whiteboard foils.

Lightbox
(optional)
Working Surface / Light Box
If the top light of the Visualizer is used (default) a synchronized lightfield always marks the pick-up area of
the built-in camera on the working surface.
The alignment of this lightfield is made for working on the working surface. Due to the oblique mounting of
the camera and the light projector of the Visualizer, the lightfield shifts to the right when the distance
between the Visualizer and the scanned object is decreased (when capturing high objects).
This means that the lightfield no longer exactly shows the recorded area. In this case switch off the light of
the Visualizer by pressing the assigned PRESET key (LIGHT) and work with room light.
Synchronized Lightfield
1. Place your subject material on the working surface.
A synchronized lightfield on the working surface
marks the pick-up area of the built-in camera.
Just place your subject material in the illuminated
area.
2. Select the enlargement required with the
ZOOM keys (#31).
3. When the image is out of focus, adjust the
sharpness with the FOCUS keys (#29).

In the following cases, the usage of an optional light box is recommended:
- If the transparency is very dark such as x-rays
- If the transparency is very wavy and causes
reflections
- If the room light causes reflections on
transparencies
When an optional light box is in use, the light of the Visualizer should be switched off.
This
has the disadvantage that the synchronized lightfield of the top light no longer marks the pick-up area
of the built-in camera.
