Scanning 4x5 films, I think a true resolution near 2400 would be a good
target. Even 1200 is still usable. The bigger issue for me is getting a
high true Dmax of at least 3.6 to 3.8 (actual, not theoretical
specification). This would cover the majority of colour transparency
films.



A Dmax of 3.8 by itself is not a problem, it is having the dynamic
range to do so with out complete loosing the Dmin at the same time.


Wonder if you could do what I've seen recommended for obtaining a wide
dynamic range in digital photography.

Take two scans of the same 4x5, once for Dmax and once for Dmin and
combine them using Photoshop.


That is sort of the idea I was briefly explaining above. It works a
little, though the combination file is still a bit of a compromise.
Figure that if you have to do lots of these, then it could be a real pain.
