Re: [APML] For Wei-Hao :) Will a real astrophoto film please stand up.

Salut Dom

The reciprocity failure seems to be pretty high with the film. If you
compare the first image from the sagittarius region ( 6 min @f/2.8) with
the sencond to last (12 min @f/3.5) there is a huge difference in what
the film recorded.
The reds are still coming through but everything else seems to be lost.
Might be a good candidate for hypering.
