Walter:(posted 9158 days ago)I have some recently discovered info that may or may not be of help to you. Anyway, It is some new info for all tech pan users. The ultimate developer IMHO for tech pan is diafine. I just started using it on 2415 and I am getting super full scale negatives at an E.I. of 100. No need to worry about temperatures as diafine performs the same at 70 to 85. Non uniform development due to agitation is no longer a problem, as diafine is insensitive to agitation. The only trick is to develop tech pan in the B solution for 1 1/2 minute. I suspect that you can increase the contrast to as high a gamma by careful development timing in the B solution.
Diafine is also excellent for t-max for the same reasons. With 120 T-max 100 exposed at 320, the results are super. With T-max, the development results are insensitive to time, temperature and agitation(I just died and went to t-max heaven). You just can't screw up the development.
