FOCUS – POINT AF
The Dimâge Scan Dual2 uses the CCD sensor for autofocus.
Autofocus uses the center of the image to determine focus. Normally, this results in an
excellent scan because the film plane is flat. However, if the film is warped or curled, or if
Autofocus is turned off in the preferences, focus may not be accurate. In this case, the focus
adjustment should be performed again using the pont AF or Manual Focus function.
• Automatic autofocus can be turned on and off in the Preferences (page 39).
