  As Mel was stating 12 different exposures averaged of all spectrums should
average out. But these
are mechanical and electronic results that are being finally judged by
"your human eye" not Bob's,
not Mel's, not anybody but you. I am sure there is a way to measure a
constant  but how could you
get close to the sensitivity of the human eye with the brains interpetation
of brightness.
           I would suggest to get 12 of your friends (not ATMers) and give
them the test... And the results
would probably be just as accurate, maybe.. but then again.....  Just a brain fart..
                                                         RUSS JOCOY..
ps very interesting experiment by all means.... ("atm{at}shore.net")
