The factory rep was very direct about this. Once the raw 382 mb file is reduced to 16-bit color from 48-bit, it is approximately a 28" image printed on color paper by a LightJet without any visible fuzziness when examined critically. One gets a lot of practice fooling with the mapping curves. An interesting thing about their process is that the raw image is considered a negative and can't be changed by the software, so short of deleting the file, the original is always available. 35mm doesn't come close. Real-world 4x5 given the camera/lens/photographer combination probably has some trouble exceeding the back. I'm trying to choose words carefully here because this list is different from many in that it has real experts.
