    I have tested Forma and Lucky, I agree that Lucky has a look all of its own, the Forma I used tinted the presoak water blue so I guess that it has some anti-halation layers.

    What format was that? I was referring to 35mm, and I've never seen this effect with Foma films in that format. I gather that Foma's got different bases (and perhaps anti-halation qualities) in different formats.

    Unfortunately, water also very effectively removes sensitizing dyes, so your FP4+ would probably be more like ISO 25 than 125 after you soak and dry it (in total darkness, of course). Actually, if you *want* to remove the antihalation, it would probably work better to use water with about a half teaspoon per quart of sodium carbonate; this will swell the gelatin and let the dye dissolve out more readily. A quick dip in common stop bath and then a wash (the Ilford wash is probably overkill for this process, but a couple changes of water to clear out the acetic acid would be good) before hanging to dry will return the gelatin to a "normalized" state.

    I think it's probably easier to buy Lucky film, unless you need this effect in 4x5 -- Lucky is available in ISO 100 and 400, 35 mm and 120, but not in sheet form to the best of my knowledge.
    Photography has always fascinated me -- as a child, simply for the magic of capturing an image onto glossy paper with a little box, but as an adult because of the unique juxtaposition of science and art -- the physics of optics, the mechanics of the camera, the chemistry of film and developer, alongside the art in seeing, composing, exposing, processing and printing.

    Your right I tested the 120 format.

    You are right, I tested both Luck and Foma in the 120 format.
