The moisture that collects inside the can is a result of condensation of the
outside ambient air coming in contact with it. In other words, the moisture you
see forming on the inside of the canister and the surface of the cartridge when
you open a cold canister is a direct result of opening it!
Opening the canister allows ambient air to come in contact with the cold film
and cartridge surfaces, causing condensation. It is the condensation that forms
on the film surface inside the cartridge that is problematic.
Letting the film warm up in the unopened canister reduces the amount of moisture
that forms. Keep in mind, with the film in the canister there isn't much room
left over for moisture laden air.
Lee is correct. You are wrong. And there are lots of people who warm up the
film in the can. I've seen this advice in many photo mags over the years, and
in lots of other places.

Recently Lee Hawkins told me I was totally wrong in advising people to
remove their frozen film from the cannister to warm up and dry out
before using. His educated comment was to leave it in the can to warm
up. I had never heard of anyone doing this because it keeps the moisture
in the can with the film! An obvious dumb thing to do. However, knowing
Lee is somewhat informed, I telephoned a number of professional
photographers that use frozen, outdated film in their work. We sell to a
bunch of wedding photographers and serious amateurs who buy 50 to 100
rolls from us at a time.
It was unanimous, no one leaves the film in the cannister to warm up.
Most take the film out of the cannister and throw it into their
equipment bag right away to be ready to shoot as the situation dictates.
Most everyone's comment was, does someone actually leave it in the can?
Next time look inside the cannister and see the moisture that collectsd
there.Too bad Lee. OLYMPUS Dude.
