Sealed air-tight, light tight chamber, vacuum pump, forming gas, heat and a thermostat...

The old version of Fuji Acros is really nice if you can find any. Works great right out of the box for astrophotography. Don't have to do anything special to it. This is all just for black and white negatives though.
