    Sorry to disagree, Martin, but I have never felt an inherent curl to any sheet film that I have used. However, I shoot only Kodak and Ilford (although I have an old box of Forte to be opened soon. Maybe it will curl).

    As for the lick text, I have to say I think this is a very bad idea. The notches are there for a reason and I can't imagine a situation where making the film wet would be preferable to checking the notches.

    I agree.
    The 'lick test' would not work - sheet film usually had gelatine layer on both sides, the layer on the back holds the anti halation dye.

    Check the notches, that is why they are there.

    I'm with Martin Reed on this; squeeze the edges of the film a touch and the emulsion side bends inwards – useful if you only have one hand free, which is usually the case when you are loading or unloading sheets of film

    The emulsion side does feel stickier than the anti halation backing; this is detectable if your hands are even slightly sweaty

    I do agree it’s not good to hold the Film between the fingers but I can detect the variation in stickiness even when I hold the film edge-on

    I don't get this, but if you guys insist on checking film by running your fingers over it or getting it wet, so be it. I am going to stick with notches.

    Well I did say last resort, and I wasn't implying licking it, just using moisture on the finger. OK one more, very dark green safelight, look for the lighter reflectance on the emulsion side. But it would be tricky finding one of the safelight filters now.

    Notches aren't always there - some people are trimming film to smaller sizes for obsolete formats, (but on the other hand they usually leave the notched corner in place).

    As a darkroom tech I knew all the notches that was my first port of call, but often I'd brush my lip (not wet) against the edge of the film, you can feel the emulsion and this helps if notches are missing or hard to define.
