I've seen large prints at our local art museum - they are something to behold.

You can get similar, though less pronounced, depth in snapshots. I've shown people 4x6 prints from film and digital (just sharing snapshots) - both wet-printed at the same drug store - and have heard comments that some of the pictures have depth ("almost 3D"). Those pictures turn out to be from film, and the drug-store machine scans the negatives in order to print. As important as silver-gelatin paper is, there is still something to be said of the "capture medium."
