I've been investingating this further, and I've got some interesting things to report. Apparently, you can get remarkably good prints at, of all places, Wal-Mart and Costco. It seems these places are buying Fuji Frontier or Noritsu printers that print onto standard color photographic paper. Many of the Fuji vendors are printing on Fuji Crystal Archive paper, which is supposedly one of the better papers out there. Plus, these machines are self-calibrating, such that they can be operated by idiots.
Well, for $0.20/piece, you can get 4x6's, up to $2.00/piece for 8x10's. That's an order of magnitude cheaper than other professional printing options.
Better yet, it seems that many of these places have had their specific machines profiled. You can go to
Dry Creek Photo and check out all their data. Some of the vendors have some sort of "enhanced" profile, as well. I dunno what that means, but
the instructions are illuminating reading. They recommend that you explicitly convert your images to match the printer profiles, then save the images
without an embedded profile, lest you confuse the printer. Instead, you beg and plead with the printer operator to run your prints with the built-in correction software disabled.
Wild, huh?
