I've used Super XX in 4x5 and Bergger in 120, and have to say they seem like quite different films to me, but perhaps the difference was due to the format. They are both old-style emulsions, as has been said above. Ansel had plenty of opportunity to use Super XX, but he preferred Tri-X. Michael Smith and Paula Chamlee seem to be the current champions of Super XX (they're still using old stock), but for the life of me I can't believe it could make that much difference in contact prints. For my personal work with 120 rollfilm, I prefer the T-Max and Delta films--I get quite good tonality from them, as well as fine grain and better speed.(posted 8129 days ago)B&H sells both Bergger BRF 200 and Fortepan 200 for $2.95 per roll.
