> mess with ice(posted 8509 days ago)It's really not that bad. Pour all your chemicals into wide-mouth containers. Put some ice cubes in a plastic sandwich bag. Dunk the bag into the developer and monitor its temperature until the developer is down to around whatever your target temperature is. Then do the same with the stop, fix etc in sequence, letting each be a couple degrees higher so you don't end up making a huge jump from a cold solution to the much warmer wash water.
Rinse off the thermometer and recheck the developer; it's probably a degree or so warmer by now, so develop at that temperature.
No need to go all the way to 68F; anything below 74F-75F is fine.
Look in the Kodak tech sheets or in the Darkroom Dataguide for time/temperature compensation info to be sure you're reducing the development time appropriately. There's a one-size-fits-all formula for approximating it (perhaps someone could post it) that'll be close enough.
