RE: Flash with Infrared Film

["David J. Carlyon" <david@xxxxxxx>]

Thanks, I just hung up a new roll to dry, with 7 test shots (of my cat)
with indoor flash at the end of the roll. I did some at ISO 100, ISO 50,
and ISO 25. The ones at ISO 25 look like they're probably most correctly
exposed (and they look pretty good as far as that goes, as good as the ISO
200 ones taken outdoors). So unless upon printing they end up being worse
than they appear, I'll probably use ISO 25 for shots with my flash and a
red filter.
