Focusing the scanner - More prescan functions

Use the focusing functions if the film is warped or curled. Three options are avail-
able: autofocus, Point AF, and manual focus. Autofocus uses the center of image to
determine the focus is activated with the autofocus-at-scan option in the preferences
dialog box (p. 44). Point AF uses a point specified in the image to determine the
focus. The scanner can also be focused manually using a selected point. Point AF
and manual focus can be used for individual images.

Point AF (Autofocus)

The point AF focuses on a select point within the image. For best results when using
point AF, select an area within the image with contrast or detail. The point AF func-
tion cannot focus on a low-contrast image area such as a cloudless or overcast sky.
Click the point-AF button. The
mouse pointer will change to the
point-AF icon. To cancel the func-
tion, click the point-AF button
again.
Click on the area of image to be
used for focus. Autofocus will
begin and a new prescan will be
displayed.
