Changes in HP5
Hi Simon: A friend of mine has used HP5 film for quite a while and has indicated that he learned that there were some improvements made in the film a few years back. He always uses Pyro developer, and has indicated that since the changes ( less b+f and some "improvements" in the film curves ) he has made HP5 his preferred film. For the record, I use HP5 as well. Can you confirm that there were some changes to the emulsion a few years back, and if so, how was the film "made better".
