 Lew,  Tmax 3200 doesn't fog almost immediately...that's not what is being
discussed.  I've made exposures with tmax 3200 up to 1.5 hours and no
appreciable fog...the problem is the opposite..dot it slows down in being
affected by light..dot it's not acting like ASA 3200, but rather somewhere below
ASA 100...possibly and probably lower.  I'm looking for film that won't slow
down it's ability to be exposed to light during long exposures...just the
opposite really.
