Dear Noeyedear....

Your suggestion works very well. Emulsion on the platen, 48 Bit Color (only tried 48HDR color9 and scanned at 2.5. I also used Siverfast Ai and regular Epson Scan on the 750 Pro...very similar with Epson being easier to use. Thanks for the tip.

It is best to convert 8 bit or 16 greyscale bit to work on?

Best...
