    Hi

    Ok, I do a lot of portraits (see my folio) and thought it time I went more adventurous...
    So, grey background, big softbox, strip light and an off camera flash with a green gel.
    Took some pix of a model.. Looks ok but the green is not showing up (it's pointed on the background).
    Tried again, and again.... It's not there..... Spooky.
    With just the gel light I can see it, but with the other lights on it just looks white on the background.

    What the Hell is going on O_o weird.

    Help....

    The other lights are cancelling it out, Probably aided and abeted by your WB.

    You could try dumbing the other lights down a stop or two, What colour is the background...? That might make a change also, Especially if its the grey one you mention.

    How dark is your grey background and how are you metering and what mode of metering are you using.

    Without seeing a setup of what your doing I will take a few guesses.

    Your key light is spilling onto the background and over powering the background lights.
    So use your softbox with a grid and skim the light across the subject, that way the key light is not hitting the background.
    Or move the model further away from the background and bring your softbox really close to the subject ie just out of the frame and no more.

    If your grey background is not a darker mid grey you will end up with pastel colours, similar to using gels on a white background you get pastels. Darker grey or black will give you good well saturated backgrounds.
    Also try using a few more layers of gels.

    Hope that helps

    I've had this before, I had the gelled light on way too high and it just gave white light, despite having a red gel... turn the power down and it'll probably start looking green

    take a shot with just the gelled light first... see what you can see

    Thanks all Smile

    It's a dark grey background.
    Metered ok at f8 and f9 (looks nice slightly darker).
    Main light is high at that, so feathered it more to keep it angled off the background.
    The little flash with the gel is looking more green more that I've put it at it's widest zoom, and backed it off a little.
    Might try doubling up the gels, that sounds like a good idea Smile

    Cheers

    Try what Ade has said, I totally overlooked that point and is a very common mistake.

    Yeah that worked, it was too high on power, simple little thing fixed it.
    Normally I like solid white or black backgrounds for studio (or a blue spot) so this sort of faded light across one side is new to me lol, looking good now Smile

    here's a rule I live by...

    most problems with flash is down to batteries...


    triggers always seem to have run out of charge for some reason... or if you're doing strobist, your flashes will run out at just the wrong moment!
