    hey mabman

    the film stain is
    brownish from the caffenol + bromide
    2 or 3 frames on the entire 72 frame roll
    got the colorized treatment ...

    thanks!

    my guess is that you have something of a minor split tone going on... there will ALWAYS be some degree of that, however minor. I used to do that with Polaroid 55 neg film... print it on color paper - and you'd get a lovely subtle split... auto leveling HEAVILY magnifies any subtlety of effect...

    Q: you don't do any fancy stuff with curves when you invert the neg scan? I've found that I've had to do some really crazy non-linear curvage when trying to actually mimic a traditional print. Meaning - a straight inversion can't really capture the tonality of a print. I guess what's actually going on is mimicking the characteristic curve of the paper/dev combo...

    John,
    I have a scan of an old glass plate that came out surprisingly well toned in color though it was a silver emulsion. The computer makes stuff up, it's as simple as that. Another reason not to trust 'em.
