    Efke Aura cannot under any circumstances be loaded in anything less than a dark room
    This is the only film I have not checked out. Maybe you have to load in total darkness.

    Efke IR820, Rollei IR820/400, SFX and SuperPan 200 you can load in subdue light and for development in a standard developing tank. I am using the Jobo 15XX system.

    The 35mm versions of Efke IR820 and Rollei IR820/400 are most sensitive for the "light piping" effect.

    Wait, how would warmth from the hands affect the film?

    Because radiated warmth = IR radiation.
    Rather longer focal length, i gather, than what the film would be sensitive too.

    The old changing bag I've got specifically says not IR safe on it. So I guess it's out, too, huh?

    Stupid mistake. Wave length of course.

    I have not had problems loading 120 Maco IR 820 in a darkened room or in subdued light (indoors). I have not mastered loading my Hasselblad backs in total darkness (nor have I tried).

    The majority of my IR film usage (aside from HIE and EIR) has been in sheet film sizes (4x5 & 8x10) so I have to use a changing tent. The Harrison tents (and they do make smaller versions) have been fine for loading/unloading IR film in. I have not taken it into the field however, so don't know how well they work outdoors.

    This thread reminds me that I have some Maco IR loaded in a couple of MF cameras. I should go and shoot it this weekend.
