The reason I read this forum was that I made the same mistake a few days back. I developped the film for 7min in D76 1:1 at 20C (is that 68F?). It resulted in a beautiful soft film, actually quite nice for most of the shots I did. For metal and glass objects, (wax) flowers and playing cards (I'm doing pictures of objects from alice in wonderland) the result was pretty nice. Only a bright white teapot failed because of the overexposure. As I understand more people expose tmax 400 at 100 to get softer pictures. Also nice for portraits.(posted 8075 days ago)regards Reinier
