Thanks, John. I’m confused. Not that you’re confusing, just that the limits of my knowledge are again being tested. So the 72 dpi figure has nothing to do with the size of print that can be obtained? The latter is a function of the available pixels and the dimensions of the print? In your third paragraph I don’t understand “suggesting a crop to 2016 pixels high (for a 10 x 20 print).” I can increase the ppi for a given dimension of print, e.g., 10 x 20, by cropping the image? My assumption would be that the only way to increase the ppi would be to reduce the size of the print. Your last paragraph: You think I can get a decent 10 x 20 print from the image I described? ------------------------------------------------------------------------------------------ Eric Weir Decatur, GA USA eew...@bellsouth.net "Imagining the other is a powerful antidote to fanaticism and hatred." - Amos Oz -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
