I know the fog is not from the plate because the ambro version also had some fog, but keep in mind that this is just experimental and someone out there might take this thing and run with it and find improvements.

The only existing plate I kept for comparison reasons was a little more brighter than the Rockland coated plates. I used my own emulsion on that one and am going to see if the effect is reproducable, although the speed was a lot slower, about .7 to 1.5 where as the the speed of the actual rockland tintype kit is about 1.5.
