Certainly not the oddest question I've asked. Removing the film from the strip.

    I am working on a, as they call it "mixed media" project where I want
    to completely strip a negative clean and transfer it like an iron-on
    to another material. I'm sure there is a solvent that will do
    this...But what?

    I *could* just expose the material using liquid emulsion but I'm
    having a hard (and expensive) time getting it to come out the way I
    want it.

    I don't care, obviously, if the negatives are gone after I do this.

    Any thoughts on "transferring" the negative image only to another

    There is a technique called Poloroid transfer wherein the emulsion is
    floated off a Poloroid positive and transfered to another surface. You
    might be able to adapt this process by first photographing your negative
    on Poloraid material.

    I think Unblinking Eye <http://www.unblinkingeye.com> has article on
    this. If not, do a google search on "Polaroid transfer"

  3. Not sure how one would loosen/float the gelatin off the film backing being
    that considerable research went into making it stick, come hhell or high
    water... I suspect that a steady hand on a flat surface could use a very
    sharp razor to shave the gelatin off the backing film...

    I have seen numerous polaroid gelatin transfers, however... Do a google on
    that subject... Apparently it is quick and simple...
    Also, alternate photo processes such as callotype and carbon printing allow
    mutiple image transfers... Take a cruise through unblinkingeye.com for more
    If it is specifically a negative you want, you may have to go through two
    generations to get back to a negative - not a biggie though...

    Nope, no tthe oddest question I've seen...

    In one of Kodak's publications on restoration and retouching, they go into
    detail about the procedures for removing an emulsion from the film base. I
    don't have the book handy (I'm at work and its at home) so I can't recall
    the exact title or the CAT #. It can be done, though. Sorry I couldn't be
    of more help.

  5. Yes, Kodak might be the place to start, as they did make a "stripping"
    emulsion at one time. This may have to be searched in the "Graphic
    Arts" section.

    One roundabout way of getting a gelatine emulsion free from an Acetate
    base is to dissolve the base in Acetone. This should leave a
    perfectly undamaged image in the tray. Just get the cheapest pure
    Acetone you can.

    It wouldn't dissolve the emulsion ?

    No, I first saw this happen in a film matching facility. One Doofus
    (not me) let a length of film sit in some spilled film cement. Gone
    was the base and all there was was a magical picture, waving in the
    air in full color.

    After that, someone would dunk some scrap lengths of film in cement
    and stick it onto lamp shades. We had a lot of time on our hands

    I suggest Acetone, as it is the ingredient in film cement that does
    the dissolving. It is also cheaper as it can be gotten in larger
    quantities and isn't a specialty product.

    Cheers to all.

    That is AWESOME!

    Off to buy Acetone for New Years!

    If anyone happens to find that Kodak manual # or anything feel free to
    pass it my way. I'll keep searching..

    Ace Hardware has acetone in their paint and solvent department. NB - in
    some parts of the USA they might look at you sideways if you buy a gallon
    of it. Seems it is part of the formula for home-made drugs - meth, I
    think. Not sure.

    Well I don't stay up all night doing this drinking coffee!


    Happy New Year

  11. Glad to help you out. I have always been appreciative of your urge to
    experiment. I did this, too in my younger days.

    All I have left are memories. };-/

  12. Kewl; please report your results back here.

    Hate to sound like a nanny, but you be sure to observe the precautions with
    that stuff, you hear? Not only is it highly flammable, the vapors are really
    nasty. Stuff gives me headaches. Use it with plenty of ventilation.

    By the way, acetone == lacquer thinner, if that helps.

    Lacquer thinner and acetone are NOT the same stuff.

    (speaking of acetone)
    Here's a hell of a case: In a certain auto manufacturer's literature it
    said to clean the pre-painted fiberglass body with a rag liberaly wet with
    acetone. Great combination: static potential and a highly flammable fluid.

  15. If I walked into the local paint store and said I needed two, fifty gallon
    drums of acetone, the only question would be, "Cash or credit card, sir?"

  16. JJ, in a previous life I owned a body shop... This is SOP for prep work with
    many paint systems..... And if my alcoholic, stumble bum, body men were not
    able to blow up, ignite, char, or otherwise send the building a 100 feet
    straight up while doing this, static is not an issue...

    Thanks everyone for the info.

    Acetone is indeed in the same AISLE as Laquer Thinner..and its pretty
    rough stuff...But its no more irritating (to me) than say, Turpentine
    I use to clean my brushes. I'm not playing with this stuff inside :)

    But still, thanks for the heads-up. Acetone is messed up. I've been
    in situations where I've gotten high off the stuff and been too high
    to realise I needed to get outta there...I usually use a respirator if
    I use it for more than say..5-10 mins...

    Again, hny and i'll report back with my results...
