I did a search and didn't find the answer that I was looking for... I just developed my first roll of film using what I could find in some books and on the www. I went with the basics all Kodak; D76, Indicator Stop, Kodafix, Kodak Hypo, and Photo-Flo. Thought I would start with something easy. Everything turned out fine, I think I overexposed the film so the negatives are a little dark, and maybe they are overdeveloped a bit. The timer is easy to follow and a step by step method seemed to work. My question is that the agitation seems the main nebulous variable. If I invert (which I did) then the film is out of the developer for a bit of time depending on how fast my inversion is. I have a Patterson tank so I could use the twisting method, which I haven't tried yet. It seems to take me about 15 seconds to do 5 inversions, otherwise it seems as though I'm making a drink, which would seem to froth the developer. Does the twisting method work? Should I be doing inversions faster? Do I need a metronome, otherwise how do I know if I'm agitating the same or differently on different days? That is D76 stock and Legacy Pro 100 for 7.25 minutes. Thanks.
