    Thanks to another APUG member, I've come into the possession of a 100ftx70mm roll of Aerochrome infrared, which I plan on cutting into single sheets and shooting in cut film holders. While 100ft will give me a little over 350 exposures, I want to keep the experimentation to an absolute minimum.

    I've been reading up on false color infrared film for the last week or so, so I'm not totally ignorant. I already have a wratten #12 (minus blue) filter, though I've read that using orange or red filters will give interesting results, too. In terms of processing, I've read arguments for and against both e-6 and c41. Some said to *only* develop aerochrome with the proper AR-5 process, but it's unlikely that I'll be able to do that. I already have some C-41 chemicals, so that would be the easiest route. If I developed in C-41, would I be able to print with RA-4? I was originally planning on getting ahold of the E-6 chemistry and printing with the RA-4 reversal method as described here, but, if I remember correctly, PE said something about EIR in c41 creating a really interesting effect. C41 and normal RA-4 would certainly simplify things for me. What would the benefits be of using E-6 and printing with something like ilfochrome (which I've read is very expensive...)?

    The documentation for EIR says to meter at ASA 200 for E-6; what should I set my meter to for C-41? Do I meter through the filter or without it?

    Also, my biggest concern is accidentally fogging the roll while loading it into holders. The can is sealed and frozen, so nothing could have happened yet. Should I take any extra precautions in terms of handling it than normal color film?

    EIR has a clear base, so you'd need some kind of filter to compensate for the lack of the negative mask for "correct" printing with EIR.

    I havent tried EIR in C41... as I only have one roll left, and 35mm.. wish I had more, but its $$$$.

    Load it in a dark bag and it should be good, I've handled and opened and loaded EIR in daylight and after going through numerous x-ray macines with it, it should be all good, it's near IR not far IR, if it was far IR it'd expose itself.

    I've some films from http://www.tarquinius.de/

    But it's expensive, which is mabye fine, because it will not quickly disappear.

    But I heard from my friend, if you going to cross it ( C-41 ) he lost colors like some monochrome. ( low saturation etc.. )

    So only one way how to get interesting results is E6 ?! But there is little problem, how to make prints ( reversal paper or RA-4 reversal )...not so easy like normal RA-4. Mabye contact prints on some reversal film.

    I try to search some samples on flicker, but the opinions are various.

    So have anybody the explanation C-41 vs E6 ?

    Thanks

    My recommendation:

    Rate at 200, shoot with a yellow filter (I use a B+W 021 which is equivalent to a Yellow 12)


    Stephen Frizza was kind enough to give me some EIR (same emulsion as the Aerochrome IR - and the film that Dean is respooling from long & wide rolls)
    I would recommend you ask him for information on cross processing. He runs E6 and C41 on a daily basis.

    I am going to shoot my EIR in the next few days :smile: Just got to stop loading Kodachrome into my IR safe camera for once!

    I've been doing just about that, andrew. I just shot some today, in fact. I also ruined 6 "sheets" of it due to one of my grafmatics jamming. :sad:

    Here's one of the first few shots I took with it as a test (I've not really done any "serious" shooting with it as of yet):

    If you process the film as E-6 then I'de suggest printing it on Ilfochrome.
    The Film cross processes in C-41 nicely if you don't like the colour saturation why not push the film? Ide love to know how your friend exposed, processed and printed this film because I have found C-41 processed EIR to be Very Saturated but easily adjustable depending on how it is processed. See samples below
