Even though you are postulating complete analog emulation, just knowing that I'd be using a software designer's algorithm would send me headlong into making my own plates. People like Ron Mowry are going to end up being heroes to those of us who just won't go down that road. My wife and I are headed in the direction of solar plate photogravure anyway (we already have the intaglio press which is 'hard' part) and that will open up a host of interesting explorations that I can't wait to delve into.

If your scenario were to come to pass, it'd be fun to imagine the ad slogans:

"Just like the real thing!" "Photography's Golden Age can now be yours to recreate effortlessly in your study or family room!" "You too can be Ansel Adams with just a few mouse clicks!"
