When I first postulated that it would work just fine, it was from my experience with images from B/W 4x5 negs. Hence, hardly a valid conclusion that could be applied universally. The sample I used last night was from this digital image; http://gallery.leica-users.org/album157 Now this was whole different animal. You're more than welcome to play with settings of the image. S.
