Preset Function
Text Enhancement
The VZ-9 offers the possibility to store the current settings as a Preset and recall them by
just pressing one of the three PRESET keys
(#32) on the remote control. For storing a
Preset just adjust every function as required and then keep one of the PRESET keys
pressed for more than 2 seconds. An on-screen message informs you, when the Preset is
stored.
When Presets are stored as mentioned above, all current settings like zoom, focus, iris etc.
are stored. Contrary to this, a user also has the opportunity to assign only specific functions
such as "Negative", "Negative/Blue", "Black/White" etc. to a PRESET key. This can be done
in the on-screen menu of the Visualizer
(see page 10).
For improving the readability of text, sketches or x-rays press the TEXT-key (#37). This
mode enhances the contrast of the picture. Please note that the colors are now darker than
usual. To switch off the Text Enhancement mode, press the TEXT-key again. While the Text
Enhancement mode is on, the message "TEXT MODE" is permanently displayed on the
built-in LCD monitor.
This should remind the user to switch off the text mode when it is not needed anymore. It
should also prevent that users try to correct dark colors by opening the iris. This would
produce a misadjusted picture.
White balance
Correct white balance adjustment is important for a 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 precise 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
(#23) 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, slide light field and external light
box.
" Auto Tracking" is the default white balance setting when the VZ-9 is shipped.
"Auto Tracking" mode will
be reactivated).
The VZ-9 can be switched between "Auto Tracking", "One Push" and "Manual" white balance mode
in the on-screen menu (see page 10)
Place the slide onto the built-in light field, turn the camera
head until the slide is in the middle of the recorded image
and switch it on using the LIGHT key
(#23). The camera
zooms the slide automatically in. The camera automatically
focuses on the slide.
