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. ~Steve 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.
