After finishing my little sliding box camera I want to have a go at something a little different. I've previously tried using Fotospeed LE30 liquid emulsion but completely loused it up! Anyway, that was in the past ;0)
I've got some tin laying around in the workshop and I'd like to make a positive image on it. I've cut a piece to suit the 9x12 holders (unfortunately even the 2mm glass I used to use for glass negatives doesn't fit in my plate holders, and the tin is thin enough to use).
I've cleaned it up, and sprayed it black, and now I'd like to coat it with liquid emulsion. If I expose this in-camera (under-expose and under-develop) will I be able to get anything like a positive-looking image? Or does it just not work this way? (Development would be with ID-11, or anything that you might recommend). Does the addition of ammonium thia-something-or-other help?
