The first time I developed C41 film by myself, the cap came off the tank during the bleach/fix. Since the tank was sideways on the roller, everything spilled all over the table. I refilled as quickly as possible and tried again, the cap came off once more. I managed to open the tank somehow while refilling it for the third and final time. By the time I'd gotten the thing together and refilled, the temperature was sure to be far off and I'd completely lost track of the time. I finished anyway, and, to my surprise, I had printable, albeit difficult, negatives.
