    I know it says on the packaging that this film should only be handled in total darkness (loading, unloading etc) but once I have it in the developing tank is it safe to turn the lights on? Or do I have to develop it in total darkness also?

    Would greatly appreciate some advice on this...

    if you are not joking, then turn on the lights with the lid in place. If you are fooling around...don't turn on the lights. :smile:

    In all deference to the humor of the Wild Bunch, the concern is the IR waves can meander through standard light trap material. That's a meander similar to a sidewinder as it slithers past your boot. But I haven't seen a sidewinder, or diamond back for that matter, that can get through a tightly capped can.

    Hi Alex, I used to dev a lot of this film in the plastic tanks, and would wrap the changing bag around the tank just to be safe while processing, might have even been overkill, never had issues..

    Yeah, I'm with you Shawn. The more precise reason as I understand, is UV waves getting through the light trap on 35mm cans and through the paper backing on 120 rolls. I never took any extra precautions once I had it in the developing tank.

    That durn Wildbunch got me sidetracked in the thought process.

    I only just noticed today that Jobo promote the fact that their plastic tanks are fine for IR film processing, but I've never had a problem using Paterson tanks for Kodak HIE. Presumably you are using a light-proof tank?

    thanks for the humour... but...

    Thanks for the comments but UV and IR lightwaves getting past the light trap on the tank was what I was actually getting at. Because you do have to remove the tank lid when changing from developer to stop to fixer I was wondering if that part of it needs to be done in the dark.

    To give the whole story, I just developed a roll for a friend and the film has distinctive fogg patterns on it. I was trying to work out the cause but have since found out he shot it with an F80 which uses an IR beam for frame placement so that's what most likely fogged the film.

    Hey a new Melbourne APUGer... welcome!

    Kevin, it might be time to start that regional group :smile:

    I've processed a couple of rolls of HIE in a Paterson tank and dimmed the room lights, which I've since decided was overkill!

    Oh yes, a belated welcome here also from a fellow Melburnian, Markus.

    I have useed a lot of this film and still do. I dev it in a variety of plastic tanks with darkroom white lights on (once in the tank) and never experienced any fogging down the light traps. Some fogging is sometimes seen in the rebates with frames that have had far too much exposure. This fogging extends from the frame into the rebate and can be quite bad at times. Aslo some cameras with infrared film frame counting sensors inside will fog rebates which can extend into the frames. Check your camera for this. Older cameras are usually OK. I use a Canon EOS 600 for I/Red work. Some of the later EOS cameras (and others) have the sensors that will fog I/Red fims.

    I hope this helps?

    Neil.

    I know it too. I bought my 500 C/M and my 40mm lens there.
