    Question 11x14 Maco 820c Aura IR film

    I came across 2 25 sheet boxes of 11x14 Maco 820c Aura IR film today in my bedroom closet. I would like to find out a couple of things. First, is anyone on this forum shooting 11x14 and second, if so, do you shoot IR film? The film has an expiration date of 4/2007. It has been wrapped in the bubble wrap it came in and still in the shipping box. I cut open the duct tape enough today that I could identify it.

    I originally purchased the film to get it cut down to 5x12, but I do not have a darkroom and have never found anyone who would cut it down for me. I don't recall what I paid for it and have no idea what it might be worth.

    I didn't want to post it for sale until I had a better idea or perhaps maybe someone would be willing to cut it down for me. Hope this is ok here.

    Would be happy to assist Diane, but concerned that my IR monocle would fog your IR film. Being able to see what I am doing relative to cutting sheet film is a desired
    prerequisite. The only other alternative would be to build a cutting template that would ensure that the proper size is cut.

    I don't want to cut it, but I have a large dry darkroom in Chicago you could use.

    I noticed you are in Illinois.

    Expired in 2007 and it's just been in your closet, not in a freezer?

    Well, the IR sensitivity dramatically decreases after a year. While it may still be somewhat IR sensitive, it will be in the "chalk and soot" range, and your speed will be 1-3 ISO.

    Make up a jig, cut a few sheets, and have some fun. You have nothing to lose.

    I have cut hundreds of sheets of 4x5 through 8x10 off a 12" roll (graphic arts infrared film), it's unpleasant and tedious to do this in the dark but it's still quite doable.

    This is quite a find, if I may say so. I'm going to go through all of my closets tomorrow to see if I have something like this lying around.

    Well 2 ISO is my "normal" speed with MACO IR film (in combination with a 70 red filter). I use MACO film much older than yours, BUT I have kept it frozen all the time, I do think that that is essential, and even than I had some 35mm IR film from the very first run from MACO (well actually EFKE) kept it frozen, but it lost it's IR sensitivity nevertheless..did not happen yet with the 4*5 stock I have which is younger than that first run..

    Good luck,

    Cor

    I'm sorry to say that I don't have a freezer large enough (and never have) for my LF film, much less this film. Randy, yes, but I'm in the St. Louis metro area a bit far from you.

    The main reason I posted here is because I don't have access to a darkroom. What sort of material would be used to make a jig to cut the film?

    I cut X-Ray film often, but it can be done under red safe light. I make film cutting stops out of clean matte board and firmly tape them down to my cutting board with gaff tape. I cut all the film one direction, and then move the cutting stop to a second position to cut the other dimension.

    I have the best success cutting one sheet at a time with my very cheap Costco paper cutter.
