Hi Tom, Your assertion is correct. Bigger files make better prints. But just for the sake of clarification, I don't "downsample" my high res images. I scan 35mm transparencies at 4000 ppi, then print them on my Epson 1200 o about a 10 x7 format. Resizing without resampling gives me a file of about 575 ppi. I print that on the Epson at 1440 d[o/ Sometimes, I'll print n 11x16 with about 350 dpi resolution. But again there is no resampling. It''s just the same 4000 ppi scan blown up to 11x16. I'm currently fooling around with scans from 6 x 7 negs. I've found that a 4000 dpi scan is almost four times as big a file as a 35mm scan (around 250 megabytes). I'm going to make some 11x16 prints from one of these later this week. That big a scan should size out to more than 600 ppi at 11x16. Paul Stenquist
