More anecdotes!
Today I processed a roll of James' 500T (shot at 400) in C41 bleach bypass (because I had another roll that I wanted to bleach bypass, and I prefer processing 2 rolls of C41 at once, because C41 is a PITA, at least compared to most B&W development). Well, technically, "partial" bleach bypass, because I blix'd it for a minute. So here was my flow:
C41 dev (100F): 3:15
C41 blix (100F): 1min
Ilford Rapidfix (RT): 5min
wash (cold tap water): 5min
C41 stab (RT): 1min
wash (cold tap water): 5min
And what happened when I pulled the 500T out at the end of all of this? Remjet was still 100% ON the film! I had to scrub it off with my fingers! This leads me to believe that my last experience, where the remjet came off in the final rinses, was because the 7:15 in 100F solutions dissolved the remjet out, and this time, since I only kept it at 100F for 4:15, the remjet never dissolved.
This also brings up the question of whether the remjet interfered with developing or blixing (/slash/fixing). The remjet is on the emulsion side, so technically it could interfere with the solutions getting to the emulsion. My last experience, of course, suggested otherwise, but I am curious now. Unfortunately, this round of development can't be a real test, because I changed 2 variables (shot at 400 and bleach bypassed). Normally I only change 1 variable at a time, which is why I shot it at 400 with the intention of processing standard C41, but hey, I'm fickle, ok?
Photos to follow tomorrow or whenever I scan them.
