No, it doesn't, and I'll admit that. But the two minute exposures do bring
the tedium of the tests down to a tollerable level and they do weed out
films that are not worth further real sky evaluation.
I had forgotten I had those film tests on my web site. If anyone visits it,
bear in mind that many of the films discussed don't exist any more. I don't
plan on testing any more films until I am ready to submit data for the next
printing of Wide-Field Astrophotography. But then again, I also realize
that excercise will only tempt the Great Yellow Father and the gods on Mt.
Fuji to change the film formulation again rendering my new edition
inaccurate right off the bat <g>.
