    Hi, all.

    I am struggling to come up with a practicable way of accompishing a
    specific lighting effect, and thought I'd poll the experts.

    The model I will be photographing has a tattoo on her upper chest, just
    below the collarbone.

    I want to provide an effect whereby the tattoo would appear to be a
    lightsource, exuding light all over that side of her face and body. The
    opposite side of the face would be dark. She would be in front of a
    dark background, so the light from the tattoo would provide a dramatic
    effect.

    I had initially thought of hanging a small LED device over her
    shoulder. I would have to remove the light itself, and the wires, in
    post, but that's not a problem. The LEDs I was able to find were waaay
    too dim, and I will not have time to hunt around for more potent ones.

    I have bought a small (1.5" diameter) bulb and a dimmer, but the length
    of the bulb and socket is just too big to 'hang' over a models shoulder
    to act as a lightsource.

    What I plan do try first is to 'tape' a small foil-covered half-sphere
    on the model's chest where the tattoo is (I know this will have to be
    removed in post, but I can deal with that) and TRY to find a way to
    make the light coming out of this 50W GU10 bulb 'focus' more tightly
    than it does by default. I'd aim the bulb at the foil sphere, and the
    result would be that light would reflect off the foil sphere and
    illuminate the subject.

    I thought of placing something like a toilet paper tube over the bulb,
    line it with foil, and hope that that would help to aim the light more
    tightly.

    I dunno how well that's going to work. Depends how much light this bulb
    will put out - that I don't know yet.

    Has anyone else out there done something similar? Maybe there's a
    dead-simple solution I haven't thought of yet ...

    Thanks!!

    Have you thought about hanging a mag-lite over the model's shoulder? Or how
    about a long exposure and use the mag-lite to "paint" the model with light?

    Have you thought about hanging a mag-lite over the model's shoulder? Or how
    I could try the long exposure, but I'd like the image to be as sharp as
    possible, and I suspect she'd move slightly during the exposure.

    As to the mag-lite: just hanging the light would likely be pretty
    directional (ie light would go down and not up and out) - unless you're
    not talking about the 'flashlight' style of mag-lite...?

    Something _small_, but which would provide omnidirectional light is
    really what I'm looking for...

    Have you thought about hanging a mag-lite over the model's shoulder? Or how
    I wonder if a small Xmas ornament would work - little shiny ball, cut
    in half - what would happen if I aimed a small, bright light at
    that...?

    Why the **** do you want to glmaorize the filthy, decadent practice of
    tatooing?

    Any reason that a couple of flashheads wouldn't work here? Aim one
    from below and off to the side to get the upward lighting to contour
    the face, using a grid or snoot to control the spread. Set the other
    at a lower power setting and use a small softbox (or another grid) to
    directionally wash the tatoo and body from the opposite direction.
    That way, your shadow areas on the face should remain consistent, and
    you get light only where you want it.

    No, no reason that wouldn't work - only catch is I currently own only
    one flash. I guess I'm kind of working on the cheap here. ;)

    I'd just set her up in the pose that you want, and place a snooted, or
    focusing fresnel spot storbe below her chest (spacing depends on how tightly
    you will crop the final). Do the rest of your lighting, as you wish.

    Rather than try and find something small and powerful enough, that will have
    to be removed in post processing, use a normal strobe w/ attachments, and then
    create the "glow" in PS, or whatever. The glow from the tattoo should be quite
    easy, and you can even use its outline, extrude it, blur it, and create a "
    light beam."

    Find a good photo equipment rental shop nearby. I'll bet that so simple a rig
    would cost ~US$15/day. Otherwise, borrow what you need from a friend. Using a
    strobe takes camera shake, model shake, and the possibility of burning your
    model, or shocking her, out of the equation. Otherwise, use your strobe as the
    tattoo source with the toilet paper tube and a projector lens attached to it.
    Then use corrected tungsten sources for the fill, plus a few white flats.

    I had not received Rob's post on my news server, prior to my same answer.
    Otherwise, I'd not have bothered to essentially say what he had already
    stated.
