RE: [APML]: dry air vs. nitrogen purge

Chuck: Why do you also purge after the exposure? Is it too keep your 
hypered film dry? I'm not using hypered film and want to purge to keep film 
from buckling during exposure...so OK to let it "humidify" after the 
session, I thought. Alternatively, hold can be drilled in the plastic 
camera cap. Thanks for your help, Ben

2) If you store
the camera with a lens on it after your session, you'll still need to 
introduce
gas into the camera via the mounting hole.
