I'd do an empirical test and take an unexposed strip, develop normally and turn on the lights as soon as you'd like them to be on and compare that with an identical strip that has been in the fix a minute or so. I use rapid fix and turn on the lights within 30 secs.

DEAR LIST, Regarding processing B&W VC FB paper, I am very interested to hear at what point in the (normal, not rapid) fixer you turn on the white lights. Letʼs assume you develop and stop in your normal way and are using regular fixer. I use the two fixer method; 5 min in the first fix and 5 more min in a very fresh second fix. But most of this is irrelevant to my question: How long after you put your print in the first fixer do you feel it is safe to turn on the white lights? Do you wait the full 5 mins or do you feel it is safe earlier? CHEERS! BOB Please check my website: http://www.bobkiss.com/ "Live as if you are going to die tomorrow.
