Oh, sure. Now we have to ask Gary Reese to go back and re-do all his lens
tests with funnels. How else can we be absolutely certain the photons were
evenly distributed?
Oooooh! I think we'd be in real trouble if all the photons were completely
distributed evenly. If that happened, the photograph, if properly exposed,
would produce a very nice 18 0ray card out of a B/W test chart with lpmm
bars on it! Hmmmm, maybe _that's_ how they are made?
I do agree that Gary should immediately redo all his tests using photon
funnels to determine the magnitude of improvement they make. I have reason
to believe this is why all my lenses seem to perform better at resolution
than his test results . . . since I am a rigorous user of photon funnels.
For Chris O'Neill's benefit, I also use lens corks to keep the photons from
leaking back out after I've made the photographs. I'm also certain that
rigorous use of lens corks is a major contributor to high contrast
performance. It only stands to reason that if too many of the photons leak
out before the film is processed and they are "fixed" to it that the image
_will_ lose contrast.
