Subject: Freezing BW Film
How long can slow to 400 speed BW film be kept
If that was true most of my films would have cracked, not only from
freezing during storage, but some of them also from use in similar
temperatures.
There is, however, a story of a Norwegian expedition to Antarctica
where they used an LX being modified to roll the film the opposite way
around
Freezing will not physically harm the film if the film is
properly thawed before use.

Shel, I would strongly advocate not freezing film, but simply fridging it.
I read many years ago that freezing could lead to some emulsions cracking on
loading, but that may be a myth! I
The film will be warmed to above freezing before use. The
use of a motor or a winder would be an exception rather than
a normal occurrence. I know that film can be used without
cracking in freezing temperature.
One of the things I really love about this list is that when
a question is asked,

well below the temperature in the freezer.

If you are over 40, then you can keep it frozen pretty much longer than you
I've frozen film for the past 20 years with no problems, color slide and
print films from Kodak. The pro's at the 2 day Nikon seminar said No problem,
just give it 4-5 hours to reach room temperatures before you use it.
I've bought 20 roll bricks at a discount or short dated film and frozen
Well, not xactly ... if there's a chance that some of the
bw emulsions I like are gonna disappear, I want to stock
up. Still have quite a bit of Agfa APX 25 in the freezer,
for example.
Of course, when I get completely fed up with the digicam I'm
now using, I may buy a dslr, but only if it comes
One of the things I really love about this list is that when
a question is asked, even if there's no direct response to
it, all sorts of other information and opinions are brought
to light ;-))
Yep :)
BTW, the bit of advice about using frozen (outdated) film is, after
you defreeze it, use it
I inherited a bunch of BW film from my father that had been kept in the
refrigerator for years. Some had expiration dates in the late 80's. The
only emulsion that had a problem was Kodak's High Speed Infared, which
retained some IR capability but was really foggy. T-Max (100 400),

Why's that then? It seems odd to me.

Something like that

Shel, are you thinking of stocking up on HP5+ or TX in case
Ilford/Kodak stop making it? What a horrible thought!

If you are over 40, then you can keep it frozen pretty much longer than you
will be around to use it.
Damn, that
