In an earlier post I said that I'd just mixed my first batch of Diafine. Now that I've actually used it (on Tech Pan ala Gene Crumpler's advice) and all I can say about the negatives is WOW!!!!!!!! Such acutance! I can hardly wait to try it on some conventional films. (Now that I've discovered it I presume that, like every other product I love, it will soon be discontinued).(posted 8617 days ago)
