I can't help you much but I did try one of those modern tintype kits and
after reading the directions could not get it to work. A few years went by
and I tried it again. This time on the last plate I discovered that it was
necessary to underexpose the plate. I was making 4 x 5 plates and putting
them in a camera. That last plate had a faint image on it. Since then I have
read that the tintype process does use underexposed plates. I'm talking two
or three stops below what you would use to get a good negative.
I hope this is of some help.
