Calibrating the Scanner
1. Find or make a color negative original showing a clear blue sky, or
something similar. The original must not have too many sharp con-
tours in it.
2. Mount the original in the 36 x 24 (landscape) original holder and
set the original format in the Frame pop-up menu as usual.
3. Choose CCD calibration from the Maintenance menu. The CCD
calibration window appears.
4. Read the information provided in the CCD calibration window,
then click on Calibrate. The scanner will scan the image. When it is
done, mark the Use calibration checkbox, then click on Done.
(Note that if your scanner was calibrated at the factory, then a
warning will appear if you try to make a new CCD calibration. It is
possible to dismiss the warning and continue, but we do not rec-
ommend that you recalibrate.)
If it seems like the new CCD calibration only made your scans come out
worse, it is probably because your calibration image contained too
many contours.
You have two options for removing the effects of a faulty new calibra-
tion:
¥ If your scanner was calibrated at the factory, you can return to the
original CCD calibration by opening the CCD calibration window
again and clicking on the Use factory button.
¥ If your scanner was not delivered with a factory CCD calibration.
You can remove the new calibration by opening CCD calibration
window again and removing the mark form the Use calibration
checkbox.
