Hi,

It has been my experience that were you to drink the alcohol you might see
the world much the same way as infrared film records it ! This strategy
assumes the alcohol is safe and that you are prepared not to waste such
precious stuff by burning it.

PS

Expose the HIE as you might normally do for ambient tungsten conditions and
bracket the hell out of it !
