I goofed. I mixed up a new batch of Kodak Indicator stop bath today, and must have pulled the dilution off of the wrong line of instructions (for X-ray film or some such). So instead of 8ml of concentrate, I mixed 20ml of concentrate for 500ml of working solution. The film looks okay (I haven't scanned or printed yet), but I'm wondering if I've done any hidden or long-term damage.
