Digital BW, The Print

Close but no cigar.

The subject has been explored pretty thoroughly on the Yahoo 4870 
group.

The problem is that the focal plane for a transparency scan is a bit 
higher off the platen than for a reflective scan and the DOF isn't 
quite deep enough to give a sharp image.

Use the 4x5 tranny holder that comes with the 4870, or the 
alternative which is to cut a matt board with the correct thickness, 
approx .070, then put the tranny over that, then put a piece of ANR 
(anti Newton Ring) glass over it to flatten the tranny. One can even 
wet mount it doing this.I've wet mounted 35mm with very good results, 
however I mostly do MF with Doug Fisher's aftermarket MF film holder. 
(It blows the doors off of the epson "cracker Jack toy" film holder)
