John Hicks recently did some research with a Jobo tank and found that there is virtually no difference between the curves of film developed in a rotary tank and those developed with intermittent agitation in a hand tank. Developing times must be reduced. He wrote a brief article on it, which I have on my web site: http://unblinkingeye.com/Articles/Rotary/rotary.html.(posted 8503 days ago)
