[LargeFormat] Polaroid in cold

[Hornford, Dave]

Based on this experience taking some Polaroid on a short winter trip (say 3
or 4 days snowshoeing or skiing) with a temperature of -15 C (5 F) should be
ok - but I should put the packets inside my jacket to warm-up before
starting developing and develop inside my jacket.

My interest in Polaroid stems from an observation that both of my older
shutters get more variable in the cold and I was hoping the Polaroid would
help me know how variable - but the variable ISO and a variable shutter is a
challenge.

If I understand the ISO right.. if I shoot at ISO 100 at an ambient of 0 C
(32 F) and develop at 15 C (60 F) my ISO was really 60 when I shot the
picture?

I never froze polaroids for a long time, but i know that a brief freeze
(unintentionally left in the freezing car for a few days) did not harm them
at all.

At time of processing, the temp should be as close to ideal as possible (70
deg C) ... and it takes time to heat up the chemical pod after it has been
stored cold.  Some photographers will carry several sleeves of polaroid
under their shirt to keep them warm and will put them back under the shirt
while developing.
