Wulff ><Snip> I believe the transition was they changed the name on the box from High Contrast Copy film to Tech pan when they came out with the special developer to get fully continuous tone results with it. I also widely experimented with HCC Film shooting texture screens and you name it in the early to mid 70's. Got reasonably continuous tone results with all kinds of develers just by shooting in the shadows not getting a wide subject tonal range. Printed it on #1 Brovira 11x14's. #2 even!
