I've had quite good success using terri's method- 6 min in Tmax 1:4, inverting once per minute. I haven't developed many rolls yet (about 5 or 6), but I seem to get good results rated at ISO 200 with a #25 filter. I *do* add an additional 3 stops for filter factor, realizing it's not truly 3 stops, but it makes more sense to me and gives me printable negs. I think the short development with minimal agitation makes up for what others have done with ISO 800 to 1600 and longer development. I'll try some different things when I'm confident with current technique, but I suspect they will be similar, judging from examples I've seen of others' work. This is definitely a film where there are many ways to skin the cat! Just a note- I don't know if I've just been lucky with no pinholes, but I've been using Ilfostop with success.
