But it's a trend
This first came to my attention when someone posted
a question re this, on photo.net.
I wonder just what is happening with the double peak. My (incorrect)
hunch would have been the inverse: that the first peak would yield
sharper result: assuming the focussing mechanism had "found" the
emulsion. And the second peak would be due to the mechanism then
finding the backing material.
I'd speculate both peaks are due to the emulsion itself, and there's
just something in the nature of the focussing mechanism that produces
the double peak.
Incidentally, I'm waiting on delivery of some:
Gepe Pro Scan Mount Art. No. 7012
and:
Wess AHX500K
Any opinion/experience with either of these? Or?
I'm hoping one or both of these will improve my corner to corner focus.
I've tried some Gepe Anti-Newton Glass Mounts. I was intitially very
happy with the results. But then, began noticing artifacts in highlight
areas. Reversing the glass in a mount where I drilled out the plastic
rivets holding the thing together, got rid of the artifacts but
introduced some spectacular Newton rings!
At least the glass mounts gave me an idea of the potential there is,
with flat film in the scanner.
