What a shame, I used to make them by the dozens, and send them out to AD's as a promo, I used to really enjoy making them. that was a good twenty years ago, I still have a stack laying around, but they are mostly rejects. I had figured out how to get a good dmax, so much so as photogs used to call me up asking how I did it. I did manage to scan a few, but there were only so many hours in a day, I'm now semi retired and was hoping I could revive the old process, guess I'll try emulsion lifts!
