I haven't read enough to know what sort of calibration might be required but prior to actually running it in my developer water bath, I'll double check the water bath temp as well as the temp in my tank. If I have to run it set hotter or cooler than my target temp, so be it. At most it will need to hold the water constant for 8 minutes. I'm curious about fluctuations and will likely run a bath or two to see how constant it is.
The good news is that I'm not planning to eat the film afterwards...
Also, I think I'm going to go with Film Lab for my scan conversions.
