RE: [APML] Tech Pan 120 Hypering, Kodak Response.

George, I took two daylight shots on hypered 35mm with my very first
roll about this time last year.  I used the match needle light meter in
an old Yashica with the ASA dial set on 200 and 400.  You can see the
results here:

Looks like the film hypered to about 320 ASA or so IMHO.

Does anyone on the list have an example(s) showing the same section of
sky shot on hypered and un-hypered tech pan with the same exposure? Or
even boxed film tests (Don and Robert) showing the difference between
hypered and un-hypered tech pan.
