    HIE EIR MYTH BUSTED

    Ok has anyone else with a canon camera been told the infra red light and sensors inside the canon camera ruin Infra red films such HIE and EIR?

    Well having just tested HIE and EIR in the Eos 3, Eos 5 , Eos 33, Eos 30, Elan 7ne and Eos 300. I have learnt what really goes on. The Films do get exposure to infra red light in all models however it is only through one edge and half the sprocket holes. It doesn't come close to damaging the image area!!

    HOWEVER!!! once a film is at frame 36 do not let the camera rewind the film!!!
    or a second infra red source exposes the film!!! instead manually unload the camera in darkness and I can assure you the film will be fine.

    Canon cameras are fine to handle infra red film :-) yet even canon says in certain manuals IR film cant be loaded in their cameras. Myth Busted.

    AMENDMENT: In all tests the EYE Control IR sensor was switched to OFF!!! It was not tested weather turning this feature on would cause exposure to the film plane however I cant imagine it would.

    Hey, great news! I'd love to use my EOS instead in my old Canon FD-era camera. I'll give it a try!

    I've had no problem with HIE or EIR in an EOS-1V, with the camera rewinding the film as normal. The sprocket holes end up with a stripe down them (there's obviously a small IR LED counting sprocket holes) but nothing on the image area.
    Another day goes under; a little bourbon will take the strain...

    Hi Tim I should have made mention canon does say the EOS 1V is the only EOS camera designed so HIE and EIR can be loaded in them. that is why it wasn't included in my test.

    There are some older Canons that don't fog IR film too. Since autofocus is of no use, a $20 EOS 620 might be a good alternative to the gyrations of manually rewinding the film.

    A bunch of Nikons; Feds, Zorkis and a Kiev; Pentax 67-II (inherited from my deceased father-in-law); Bronica SQ-A; and a nice Shen Hao 4x5 field camera with 3 decent lenses that needs to be taken outside more. Oh, and as of mid-2012, one of those bodies we don't talk about here.

    Favourite film: do I need to pick only one?

    I have had similar results with my Nikon N80. After being told in no uncertain terms that is strictly was impossible to shoot HIE in my camera, I loaded it up anyway. As Steve says, only about 1/2 the sprocket hole appears to be affected by the IR sensor in the camera. I have seen no fogging whatsoever in the film. I have experienced no problem with the IR sensor on rewind.

    If truth be known, I have only shot "near-IR", using a dark red filter, not the full IR filters. I doubt it would make much of a difference.

    Of course, this discussion is pretty much academic, as the supply of HIE is rapidly dwindling. I've got two rolls in my freezer. There are another half-dozen in my local camera shop. (but at approaching $20 CDN including taxes, I'm not that desperate to hoard them)

    Cheers,

    Ansel Adams had the Zone System... I'm working on the points system. First I points it here, and then I points it there...

    Thanks for that information, Stephen! I own an EOS 3 and also fell for the rumor that infrared is out of the question with that camera.

    If you don't mind the sticky gooey shutter from the deteriorating foam bumper ruining 1/3 of your exposures.

    So, now that HIE is no longer available, do I run one of my three remaining precious rolls through my elan 7n to see if it ruins it?
