BF: Yes. Many of my slides are 20 year old Kodachromes with visible curvature. Some (but not all) have a pronounced depth of focus problem. It's easy to test: NikonScan has a focus-point tool that lets you click anywhere on the preview image to make the scanner focus on that point. If you set your preferences to auto-focus whenever you set a new focus point you can see the numerical value of the manual focus slider change each time it auto-focuses. On a problem slide all you have to do is set the focus point on the center and do a scan then set it on an edge or corner and do a scan. The results are crystal clear: the scan is sharp where you set the focus point (e.g. in the corner) and fuzzy at other places (e.g. in the center). >It would be interesting to compare dynamic ranges of FS4000US and SS4000 >though... BF: The shadow detail (and by implication the dynamic range) on the Polariod was noticeably better. -- ====================================================================== Bill Fernandez * User Interface Architect * Bill Fernandez Design (505) 346-3080 * [EMAIL PROTECTED] * http://billfernandez.com ======================================================================
