Critical Sharpness in Digital Prints This is just a vague question overall, but even though I've read several intro-type books on digital imaging, all of which say you can get spectacular digital prints w/the right equipment and techniques, I've never seen a digital print that I would say has "critical sharpness". Now, maybe this has to do w/the prints I've seen , but we have a dye-sublimation printer at work and even these seem unsharp, or at the very least sort of "flat". Why is that? Am I just too picky? Thanks.

Would you say that the photos while on the screen are sharp? I have a photo of a leopard, which started off as a 6x4, and digitially enlarged to A4 size. This was printed on a consumer quality inkjet printer (1200dpi x 2400dpi) In the final print, you could still count hairs on the leopard if you were that patient. Now *THAT* is sharpness :)

It depends on: -the source. A great print scanned on a good scanner, as Ken did, and 300 ppi (240 minimum on an Epson) fed into a good printer, should get you true sharpness. The best way, IMHO, is to scan from the negative or slide at a resolution that will give you about 300 ppi in the output size you want. Of course, the image on the print OR film has to be sharp. -when digital images are re-sized, resampled, or otherwise messed with, you must do a final sharpening. In Photoshop (full-blown or LE), that's Unsharp Mask, under Filters/Sharpen. A print never looks as good as a projected slide, a slide on a light table, or an image on screen. They're gonna look flat on paper.

A basic question here Elaine... Are you talking about a digital print from a digital camera or one from a film scan? Jaymes

Jaymes - Both. Though I mean more from a scan of a neg or slide. Elaine
