    loading IR in the light? use a tent?

    hello,
    what do you guys do about loading your IR film in daylight? i read you can fog it that way. what are your experiences? i have shot IR before and done a "quick change" and did not think i saw any problems....although i have small black spots on my film! it was barely expired, two different processing people (me and another) so i am not sure if it was cause it was expired or what. it did not seem fogged but spotted badly. i used hc110 to develop it.
    should i worry? how about using a harrison tent? any thoughts? ideas? suggestions? i will be using it at a wedding this coming weekend.

    thanks

    I've only shot IR in 120 format. I've loaded/unloaded it in subdued light, usually turning my back to the sun so that no bright light gets to it, never experienced any fogging. I've not shot IR in 35mm, but I've always read that you need to load 35mm IR in complete darkness.

    Which IR film Eddie? If its Kodak HIE then the book I've got says: Load in complete darkeness. Likewise for unloading and place in special cassette until ready for developing.

    In the field so to speak would mean a changing bag or finding a light tight room.

    Same advice given for Maco. Only with Konica( is it still made?) and Ilford SFX can you get away with subdued light.

    I load the Rollei stuff in subdued light i.e. shade. I used to use a changing bag, but found that unnecessary. It is important to make sure that it is tightly wound (speaking of 120 film now), and it did reveal some gaps in my darkslide lining!

    Harrison tents are not IR proof. Trust me on this one.

    One should used a rubberized changing bag but they are hard to find. Many of the inexpensive bags are nylon which in some cases is transparent to IR.

    I have used a dark cloth over a sweatshirt (big one) under the shade and I have been successful, but I wouldn't rely on it.

    The black spots can be from your pressure plate if they are uniform, btw. Some people cover it with a smoother material to get rid of the "spots".

    Best of luck,

    thanks so far. the spots show up more on certain frames. maybe the pressure plate is to blame. i am shooting HIE 35mm. what could i use on my pressure plate? now i am beginning to worry about solving this problem. i never thought about the pressure plate! damn! i am shooting an N90S.

    Ha! I know! It sucks.

    Some use a piece of black electricians tape, others use foil (like aluminum) tape. I don't know which does which as I haven't enjoyed the problem.

    Anyone? Anyone?

    Kodak HIE: I fogged about 6 frames when I loaded in subdued light. Never fogged in a change bag (rubberised, is ther any other sort, I've not seen one, readily available i camera stores here) or darkroom with safelights off (many rolls).
    Maco 820: 1 roll, seemed OK in daylight despite the instructions which I didn't see to load in darkrness.
    Black spots: are they on the film or prints? Pinholes do occur in HIE which gives black spots on prints. Seems to relate to how long film has been stored unrefrigerated: longer = more pinholes.

    Dave,

    One issue you may not be considering is the lack of anti-halation layer in the HIE. Light seems to hit it and light pipe down the roll. Some have found an entire roll ruined from it. Others have found that the felt used on the canister can either reflect or absorb IR. This has had some effect on what has happened to the leaders and beyond on IR films.

    cheers

    I expect it is a bit of both but mainly the fact that the felt is transparent to IR, if you photograph black textile with HIE it normally comes out white or at best very pale grey, i.e. the black dye (mixture) is not IR opaque. I expect the felt is likewise not IR opaque. Fortunately it doesn't matter, just load in complete darkness or a change bag and no problems with fogging!
