Re: [APML] RG200 Alert

Thanks Mike and Joe,

I missed the Kodak announcement, but have the new tech data now.  My tests
show that RG200 hypered in the cassette 12 hours @ 50°C  and 3 psig is still
a very good film.  It is still better than Supra400 for shots of an hour or
more.  It has a unique property that there is NO RECPROCITY after 1 hour (
and very little loss after 17 minutes).

I have posted my quick film test results comparing the "Old" and "New" at
http://home.nethere.net/mpd/FilmTestData/RG200comparison.htm
