The Konica IR will be very fogged. I bought 40 fresh rolls when it was availble shot about 6 then froze the rest. 5 years later with the film about 3 years past date I shot 2 tolls and the fog was so high nothing ws printable. I tossed the remainder. I would not buy any Konica IR.
I've got a bunch of 120 and 4X5 film dated from around 2000-2005 that's been stored in a fridge. A lot of it was pro film that was bought "in date" from a store that kept their film cold stored. It ranges from APX-25, Delta 100 and Konica IR 720 to Kodak E100s and Fuji Astia 100 E6 films as well as some Kodak 160VC and Fuji 800 print films.
I've been shooting digital for years but have gotten the bug to go shoot with my old Rollei and maybe try 4X5 again. What's the chance this film is worth shooting today? I've read I should probably over expose it, if so any guess as to how much?
Maybe Georgia has more cosmic rays then where Andrew and revdoc spend their time.
I went back through my negatives and found the120 size Konica IR I first shot. It was May of 1990 and I was living in Illinois. I froze about 34 rolls then and it stayed frozen until 1995 when I tried using it again in Georgia. Except for two weeks in 1993 when I moved to Georgia the film was always frozen. I had ordered the film from Shutan Photo in Chicago and at the time Konica made it only once a year. 40 rolls was the minimum quantity that Shutan had to order so I bit the bullet and ordered the 40 rolls. I *think* that this was the first or second run of the 120 film and I waited six months or so to get it so I would have ordered it around Nov/Dec of 1989.
It's interesting that revdoc & Andrew O'Neill had much better luck with it than I did. I suspect that they had later production stock than I did. IIRC Konica discontinued the 120 IR film around 2004ish so it had about a 14 year run.
I would be wary of any Konica 120 IR film that had an expiration date of May 1992 or earlier.
I have always liked using IR film and this was a huge disappointment for me. I have 5 rolls of of the Rollei I20 IR film to shoot. I also have 18 rolls of Efke 127 (yes 127 for my Baby Rollei 4x4 !) IR820 film that expired in Mar 2008 - I developed a roll last week and it is fine - no fog.
I bet it'll all be fine.. I've been shooting 4x5 Kodak HIE that expired in 1967. Kept in a freezer. The base fog is a bit high, but I am still able to use this wonderful stuff.
Sir Andrew..
Just invested in a new freezer and, on filling I came across a 'brick' of 35mm HIE that was stored for a number of years at -30°C until put into my 'old freezer' about 3 years ago. Now wondering if it might still be 'OK'

There's only one way to find out... and that is to send them all to me.
Hey Stephe,
That's a great report. Do you still have that 8x10 Agfa 25 I sold you many years ago? That should be awesome for contact printing if you still have your 8x10. I shoot expired frozen B&W all the time.

OMG! lol How have you been?
"...freeze thaw cycles." I don't think so. I think the evaporator plate is separate from the refrigerator and the freezer compartments. Thus the evaporator can be heated a little to melt accumulated frost without warming the cooled compartments to any significant degree. This is generally the method, see also: https://en.m.wikipedia.org/wiki/Auto-defrostI routinely shoot TMY 4x5 sheets stored in a fridge expired in 2001. I would be more hopeful for the black and white. But it really has been stored in a cold shielded place you can probably use it. If it's been in an auto-defrost domestic fridge that's used for food. These see freeze thaw cycles. Best test .
Depends on the unit. I worked for Amana Refrigeration for 18 years. We ended up being bought by Maytag which was bought by Whirlpool. There is a cal rod heater in/on the evaporator. There's a thermal cut off switch to keep the heater from getting too hot. Modern refrigerators use adaptive defrost, the number of door openings will help to decide when the heater comes on."...freeze thaw cycles." I don't think so.

We like to buy tuna steaks frozen in their cryovac wrappers. These are stored without decrease in quality in our 40+ year old Kenmore top freezer frost free machine. Months after purchase the steaks, which we thaw and sear, are fine. At one time the Kenmore somehow got unplugged for a few hours, the tuna steaks, while edible, were damaged from the thaw and subsequent re-freezing. As always, YMMV.

Hang on to that refrigerator, that was made in Evansville IN by Whirlpool (originally Republic Aviation P-47 Thunderbolt plant WWII). It's not as energy efficient, and it's loaded with good old CFC Freon blowing agent and refrigerant. No reason why it won't last another 40 years. Whirlpool closed that plant, highest quality in the entire company, moved production to Mexico. I'm not sure anyone makes a decent top freezer refrigerator any longer. As long as the refrigerator is recycled at end of life, it's hard to imagine a more environmentally friendly product.
