I have come across a problem in the last bunch of film that I shot. I usually rate Bergger BPF 200 at 64 and for some reason my meter inadvertantly got shoved over to the 6400 number. I know that you all know how to "push" film but I don't know the first thing about it. So, anyway, I figured that since I was developing by inspection that I would be able to handle this... I mixed up a fresh batch of developer and since I admire both Michael Smith and Ansel Adams work I figured I wouldn't go too far wrong by mixing a up some HC110 and ABC pyro and combining them. The problem that occurred was that it was late and I spilled my coffee into the darn developer. A nice touch, but I figured that I need to account for the extra volume of water added via the coffee. So I added some more of A and then a little B...or maybe it was the HC 110 dilution B.... Now when I turned on the light, my film went black...what happened?
