    I would be interested in how you got this graph on an equal energy basis. They are not easy to do unless you have a spectrosensitometer.

    Lucky B&W film is unique in the market, and based on this news I'm considering buying up a couple bricks. You'll notice when you develop lucky B&W roll film that the presoak is clear. There is no antihalation coating on the film. This means that strong highlights tend to bloom which I think it neat. It's sort of old-time dreamy looking. On the down side it's pretty low contrast. First time I ever reached for the 5 filter was on a Lucky frame. FWIW a completely different company makes Lucky enlargers. I have one but don't use it much anymore. Part of me wants to print some lucky film on the lucky enlarger!
    One of my Lucky film shots:


    -edit-
    @3.49/roll for a 10 roll brick on ebay shipped, it's the same price as Fuji Neopan Acros before shipping. So it's not the awesome deal it once was (I got 20 rolls expired that I'm still working on for just under $2/roll).

    The absence of colorisation of processing baths does not necessarily mean that there is no anti-halation layer.

    Correct. I believe it's sensitizing dyes, not anti halation, that cause the color change in the developer or pre-soak.

    It could be acutance dyes or trimmer dyes in the coating.

    I just normalised the highest peak sensitivity to 1.

    They're comparable to their peak sensitivity of 1. It's a relative value and not an absolute value.

    It allows comparison of spectral sensitivity distribution.

    Not necessarily for graphs made by means of wedge spectrometers...

    In reply to a earlier query raised in this thread, the Lucky B&W film is not the same as Shanghai GP3. They are entirely different films made by different manufacturers.

    Lucky 100 was some of the first BW film I shot on. Stuff was interesting and I got some good shots with it. I'd buy it again.

    Luck New 100 was based on Tmax technology accordong to the joint Kodak and Lucky Press release at the time, published in the British Journal of Photography and the financial pages of the UK newspapers However at some point Lucky reverted to their own emulsions again and later the partnership with Kodak was dissolved.
