Martin, that is really interesting about C-41 development in normal tanks. I thought that colour film was much too temperature-sensitive for that, so I have all these films sitting around waiting for a decision on a Jobo, or professional development. Could you speak more about this?
The developing itself is just as easy as with B&W, but you have to heat the bottles and the tank with a water bath. This takes a while, and is more or less a PITA.
For my last roll, I just left everything in a bath at 50ºC for a while and started the procedure when the temp was right.
The developer is the only critical step, and it lasts for only 3:20 minutes or so. But it also means that the temp won't change much if you keep the tank in the bath inbetween agitations (once every half minute).
The chemicals can be used for 10-15 rolls or so, but some people have reported that it works fine for up to 25 rolls. Probably this won't be the case with fast film (400 or so), since it will exhaust the developer faster.
The whole procedure is standardized, so you use the same time for any film unless you are pushing it. Essentially there's only three fluids, but I've added a stop bath after the developer, to keep contamination of the blix as low as possible.
