    Are bags inside of Photo Paper boxes completely light tight?

    Well the question is simple. For instance if photo paper was stored in one of these "black bags" that come with photo paper only.. would the paper be ok? If this helps the paper in question is Ilford.

    As a short-term-emergency-stop-gap-no-other-option-wrapped-up-tight-and-never-exposed-to-room-light method of storage? Sure. But light can leak in through corners not sealed COMPLETELY. And if the bag were to tear slightly, thus avoiding detection? I wouldn't risk it myself for normal storage.

    And what if the bag itself (with paper) was exposed to room light for an extremely brief period? Ie. 3 seconds. The paper is somewhat new so I doubt the bag is ripped.

    I've heard of the bags being light tight, hence my confusion.

    Probably not. We have all made that mistake for longer periods of time.

    it sounds like you have paper that has been stored this way for some time. I would take a sheet from the top and from the bottom. Put it straight in the developer and process it. If yo have dark spots/edges then there has been some exposure. If not, you're good to go.
    Thank you.

    Thanks Chris but,no, the paper was only exposed for a number of seconds (a short number). I don't have access to the paper at the moment so, I was just wondering.

    I find bags that have been re-used several times will develop holes in the corners where they are folded and unfolded.

    I have some large rolls of paper that I am cutting up, but am limited by the bags and boxes available, so I have been picking these things up where I can find them. Now, don't pee your pants laughing, but I test the bag for light-tightness and pinholes by putting it over my head and looking for leaks. In absence of pinholes at the corners, I would say the material is light-tight.

    I wouldn't assume that. I had a new 25-pack of paper that I opened up in the light to get the spec-sheet. When I got into the darkroom to do some printing, I found that every sheet had fogging on one corner. I looked at the bag closely and sure enough there was a small hole. It can happen.
