the results and save them for future reference.
To obtain the best results with optical defocusing, apply it during
preview scanning, rather than waiting until the final scan. The reason for
this is that the highlight and shadow measurements, which are based on
the preview scan, are affected by the focus. If you do use defocusing
during preview scanning, remember to reset the Focus Elevation to 0
afterwards.
• Focus Elevation and Autofocus can be used at the same time. In this case,
the defocusing effect will be relative to the Autofocus point for each indi-
vidual scan.
• Setting the Autofocus point manually: When Autofocus is on, ColorQuartet
automatically finds the best spot in the image to use as a focus point.
However, in some cases, you may want or need to choose the focus point
manually—for example, if the original is not equally thick all over or if there
is dust between the original and the mounting plate. Use the following
procedure:
1 • Macintosh: Choose "Focus" from the menu at the bottom of the
feedback window.
PC: Click with the right-hand mouse button anywhere in the feedback
window and choose "Focus" from the menu that appears.
The window will display the focal plane of the image. A
blue cross marks the automatic focus point.
2 • To change the focus point, click on the desired spot in the image.
Choose a spot in a light area, as these areas correspond
to the parts of the image where there are transitions
between dark and light. The lighter the spot, the more
information is available to the Autofocus function.
