Tri-X and just about every other film emulsion made by a major manufacturer is different than 40 years ago. As I understand, the principal differences are reduced silver content, finer grain and reduced development times. I think there probably are many, many subtle changes in film technology that we are unaware of. I am not opposed to improvements and I like to be able to produce reduced grain prints when I want. I also welcome the chance to use the European "retro" emulsions of Forte and EFKE.
