Upsampling always results in some loss - it might be artifacts, it might be loss of tonal gradation. My math was late night error. My practical experience is that I have yet to see a digicam image of less than 10+mPixels that looks as good printed at 11x17 as 35mm scanned at 4000dpi printed to the same level. It might simply be that the regularity of digital artifacting is more noticeable than grain. It just doesn't look that good.
And this includes images others have raved about. It may also be a matter of what you look for in an image and how experience/biased the viewing eye is. ----- Original Message ----- From: "Bob Frost" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Tuesday, October 21, 2003 7:01 AM Subject: [filmscanners] Re: Pixels and Prints Eugene, 240 dpi is not all that is needed, because the Epson driver upsamples that (or any other dpi you send it) to 720 dpi (desktop printers), using Nearest Neighbour type upsampling. So 720 dpi is what is needed by the driver. The question is can you get better results by upsampling to 720dpi yourself (using QI for example that upsamples with various superior methods - bicubic, lanczos, vector, etc). You seem to be suggesting that you can't, but others suggest you can.
