2 Yr Old Undevoloped Maco IR 820c - Any Good?

**Andre Noble** · 1-Sep-2009, 09:30

Hello,

I exposed 20 or 30 sheets of Maco IR 820c sheet film about 2 years ago, and have kept the film in the fridge/freezer since because I moved into a really tiny apt. and have been unable to set up my Jobo/darkroom.

For any IR sheet film users out there - what kind of luck will I have when I do finally develop these sheets?

I know there wouldn't be a problem with normal B&W sheet film, but this is IR.

Thanks in advance for your musings...

Well, you won't know until you develop it, will you? I can tell you it will be fine or it won't but that doesn't really matter, does it? In my own experience with that film, it's been fine.

my guess is that you will not have any issues with it. I found an exposed roll of it in 120 that had been sitting in the bottom of an unused camera bag at room temp for at least a year and maybe two. It developed fine.

Again, not really answering your question but I have been using some outdated Maco 820 IR for a while with no visible problems (not even refrigerated). I haven't delayed processing more than a month or so but I wouldn't anticipate any serious problems.
