Hi Bob, I was on the Epson list for a long time and this is the first time I've heard someone make this statement about the internal behaviour of the Epson driver. Can I ask where this knowledge comes from? In the past I found a formula written by Epson themselves which gave the optimal ppi for photos as 240ppi. I'm also wondering how the figure of 720 ppi you state above is unaffected by the model of the printer. The old Epson 3000 was only "720 dpi", and most of the Epson printers are "720 dpi" in one direction. But some of the recent printers are "2880 dpi" in one direction. Does the magic number still apply to the most recent printers? It sounds surprising that it would apply to every Epson ever made. This isn't a flame - since I have an Epson 1160 myself, I'm interested in anything which might give better results. Rob PS Someone else asked about the method for scanning a whole film with the same settings in Vuescan. I beileve you need to look at the advanced workflow information on Ed Hamrick's website. There is a setting in Vuescan to lock the exposure. ------------- How do you know if you never try?
