    Yes. Stick with the Heliopan 715 (which is equivalent to an 88A, I believe) I have also used a Wratten 87 successfully, but I like the results I get with the 88A better. You should be able to get good results with it. I shot this picture back in May with my 6x7 and an 88A filter.

    And though this isn't a stellar example, I shot this with my 8x10 and an 88A filter just before Thanksgiving on a day where it was nearly sunset and there truly wasn't much light left (and it was overcast in the first place). It was simply one of those days that I had to get out of the house and take some pictures.

    I used MACO IR 820c and a Lee 87 filter (and a 210mm Xenar) for this one:

    Yes. As others have noted, the cutoff of the 87c (850nm) is too high for Maco 820C. You'll want the cutoff point of the filter to be lower than the sensitivity point of the film - in this case 820 nanometers.

    Personally, I like the look of this film combined with a Wratten 89b filter (B+W 092), which has a cutoff point of 720nm.

    I hear that a lot when I take an IR pic into my camera club meetings. They always say they'll give it a try, but they never do. Oh well. More fun for me!

    I've also tried the Lee 87 filter and it works fine.

    IR Filters & Films

    FYI, here's a table of the various IR filters and film sensitivities:
