Hhhmm...

Sounds like this may be a great opportunity to use Portra 800 or Supra 800
(apparently the same emulsion). Fast speed and high rate of reciprocity
failure. And more exposure latitude than slide film, and as Portra 800 for
those with the right equipment, available in medium format ;o)

meteors, too, which means they're even harder to catch on film.
