1 hour, 30 minutes (Stand developed) at 20°C/68.0°F
Three dev cycles at 30 minutes each, stand. In a fully loaded stainless tank (increments of 240ml), this gives three cycles of 2ml of concentrate per roll each, or the 6ml recommended minimum recommended by Kodak. My tests were metered for 6400, and bracketed Â±1EV. In reality, I was only happy with the -1EV shots, hence the nominal rating of box speed, 3200.
