My recent experiences show without a doubt that if you
want a long lasting film, use Supra400. A 330 minute
shot of the Bubble area showed much more than a 160
minute shot. Not close, no comparison. If for some
strange reason you need a film that keeps recording at
a strong rate after 3 hours, Supra 400 is the film. I
shoot at f/10, adjust accordingly.
