Perhaps No. This isn't the case. There are fundamental limits to how much you can compress data and still be able to reconstruct it. Information theory tells you this. On the more general question. It is interesting to me that there are, right now, 4x5 scanning digital backs (BetterLight) that have reasonably high resolution (8000x6000), and can actually hold more contrast (e.g. 9 stops as opposed to 4). The main problem with them is that they need a lot of light and long exposure times to use. Storing the digital files in the field, and getting decent prints out of them cheaply are also still big hurdles. View camera magazine did a write up on these backs. It was interesting. Pete
