Hey Aggie great help....so it does work? have you found out any gross errors? like say your negative was underpoxed by 1 or 2 stops, or does the system work close enough. I mean 1 stop to 1/2 stop error, who cares....but 2 stops would have me worried.

BTW I can tell you that the B+W filter factors are very unreliable. These are the filters I have and they consistently underxposed the image. I hate that, I rather overexpose and work in the darkroom than have that morass (emphasis on the last syllable) of featureless black.....
