Re: [APML] Speeding up film - examples
The 20c test sample will be done in doors. In Montreal when the temps go
above 20 the seeing sucks. Unless you luckout and catch that magic
window right after a T-storm and the skies clear during the dark of the
moon. Saw it once back in the 70's....
Unless our weather improves, film testing or lunar work is all I will be
able to do.
