hi, I'll have to double check, but i think some of the prints were from 5x7 crops - iac, you're correct in thinking image area not paper size. what does it mean to "upsample" and what does that do to the final quality? I think it was Paul who mentioned that with digital a lower ppi can be used than with film. the biggest concern is what happens to the image when printed that large with less than a full frame, like a 5x7 format. the files i deliver to the lab have a minimum of 330 ppi, sometimes more. i don't use or make inkjet prints, rather the lab uses some frontier and lightjet machines - one uses something really high-end - bill robb was impressed when he learned what it was. i don't remember much about the specific machines. got the tour of the labs, assured myself the equipment and skills were acceptable, and soon forgot the technical details ;-))
