We have a digiview system setup here in West Chester, and its very nice.  We
have an old B&W camera from the lab set up in a copying stand and I've played
around with it some, though mainly using the HAM algorithms and the filter
wheel.  The digitization is very noise free, and anything without large color
jumps looks fantastic in HAM (expecially portraits).  I haven't tried the 
hi-res mode, but the HAM routine appears to be just an elaboration of that.
The HAM software takes a sample through each of the three filters.  Once 
captures (about 10 seconds), each sample id processed with a contrast
enhancing filter, which results in a very good looking B&W image.  When 3
of these are sampled, a HAM image can be generated and saved in IFF.  On
very contrasty images you can get better results by generating a 32 color
image instead of the HAM image.
