[Leica] tri-x at 204800 ASA

[kcassidy at asc.upenn.edu (Kyle Cassidy)]

when in college, i made a startling discovery. if you developed tri-x at 6 
minutes at 70' (or whatever) you got properly exposed negatives. if you 
increased this time to 14 minutes at 71', you could increase the film speed 
to an incredible 16,000 asa. using my failed high school math skills, i 
realized that if i cooked a roll of tri-x at 72' for seven hours, with 5 
seconds adjitation every 60 seconds and changing developer every 30 minutes, 
i could boost the film speed to 204,800 asa and shoot in side of a bank safe 
with the doors closed.
 
sadly, all i discovered was that any actual useful film speed seems to stop 
at about 64,000 but what does happen is that many parts of the negative 
become completely opaque.
 
put that in your digital leica and shoot it.
