Nope, nothing like that but I don't feel that I really need it at this point, I wouldn't know where to get those transparencies here in Belgium, it's a wasteland here in terms of photographic specialties.

I did longer exposures (see attachment), this is a 30min exposure with my UV light source, it however doesn't have much difference with the 20min exposure I did so maybe 25min will be the benchmark for me. I'm very pleased with the result, it looks a little better IRL than scanned.

Had some contamination from my brush but that will be eliminated with better cleaning procedure.
