The Preset 1 can be recalled by pressing the FREEZE key (#29) on the camera head for 2

seconds.

For storing a reset adjust y function as required and then PRESET key

for 2 seconds . An on-screen message inform you when the

reset is stored.

The presets can also be stored in the on-screen menu.

As mentioned above, when presets are stored all current settings like zoom, focus, iris etc. are

also 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 in the on-screen

menu of the Visualizer (see page 13).

Correct white balance adjustment is important for exact color reproduction.

"Auto Tracking" is the default white balance setting when the Visualizer is shipped. 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 "Auto Tracking" mode will be reactivated). When the

lighting conditions change (e.g. light box, sunlight or different room light) the white balance

should be readjusted!

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) 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 (if

available).

White Balance

Preset Function

Please note that objects with very low contrast (like blank sheet of paper) are difficult to focus. If

the autofocus does not work just move the object slightly.

For special applications the autofocus can also be switched off using the on/off switch (#28 or

#36). The autofocus is also switched off when the manual FOCUS keys (#27 or #37) are used.

Please note that the Visualizer has an optical 12x zoom. The digital 2x zoom increases the

overall zoom range to a 24x zoom. The smallest pickup size on the working surface without

digital zoom is 23 x 31mm (0.91" x 1.22"). When you zoom in further the digital zoom is

automatically activated and the smallest pickup size is 12 x 16mm (0.48" x 0.62"). However

please be aware that when the digital zoom is used, the resolution of the picture is not as high

as before. The default setting displays a message on-screen when you are in the digital zoom

mode.

Still pictures in the memory can also be digitally zoomed.

You can change the behavior of the Visualizer in the digital zoom mode in the on-screen menu (see page 13).

Autofocus

The Visualizer offers the possibility to store the current settings as a preset

and recall them by just pressing the respective PRESET key (#33) on the

remote control.
