For some strange reason (insecurity?) I just wondered why my negs weren't the same as everybody elses. And judging by Nige's message he was also a little unsure as to what to expect.
I mentioned in an earlier message that I had experienced the same pink cast that you saw with some FP4+ film, but not with other batches. I am still trying to figure it out?
Best I can do is repeat that we Pyro folks believe in magic, and some things only happen in the unlikely circumstance when both the Sun and Moon are in south declination at more than 23 degrees and 10 minutes, and within two degrees of each other in both altitude and azimuth.
Well, to be sure the pink case appears to come around more often.
Hope this clarifies the issue for all concerned.
