Hey every one!
I am new to the site and this is my first post. My problem is I shot using a green screen and have a green cast on the pictures. I am not sure how I got it or how to remove it, I am going to try to inclose a picture to show.:dunno

    The green paper on the floor has reflected light back up onto your subject.

    Not sure about a fix though.

    One thought... once the people have been extracted, they could be subjected to a dose of either hue/saturation and/or selective colour on the greens.

    Ditto on "It's a reflection from the paper".

    Which program are you using to do the extractions (assuming you don't want a green background) and have you been satisfied with the results?

    I am using CS2 and I am not very satisfied with the results! cutout seam to go okay, but getting the green hue, out is a real pain.

    Did you try a black/gray back?
    For the cutout purposes and non-raven-haired caucasian people wearing bright colors black/gray backdrop may work just fine (at least no color shadows) ne_nau.gif

    I can't help the hue problem but (caution thread hijack) what method are you using in CS2 do the extraction - the "Magic Wand" to select the area to remove or the extract filter or .......

    Try the background eraser thumb.gif That should work well with the green screen. May even be able to take out some of the green reflections from the ghis.

    We seem to have moved away a bit from the original OP's question which was about removing the green cast on the children's clothing. I think he is okay with the extraction bit.

    So, money where mouth is... I made a rough selection using a colour range selection and pasted the girls onto a new layer (I left the whole picture on the background - no cutting out stuff). A simple hue-saturation adjustment of the greens - slider all the way to the left + an adjustment to the yellows of about half way, seemed to do the trick. Flattened and saved. Time taken about 1 minute, most of which was the selection/pasting to a new layer.


    On a larger version and taking a little more time, I am sure the result would be better.

    If you have a chance to do a little practice shooting with the GS...try cutting down on the light...not knowing your set up(usually the eyes tell at least part of the story) ...either cut the lights output by the out put controls or try a different umbrella set up...if using shoot-thru go for bounce, if using silver change to white....etc.....You should be able to find a compatable set up that will work and save you PP.

    A magenta photo filter move in PSCS2 will help remove the green cast, or you may adjust the curve in the a channel in LAB.

    Use an adjustment layer with either method. You can then control the local areas of application by using a layer mask and painting in with white or black as needed to correct the correction.

    Shooting white wedding dresses on a golf course frequently will give the same reflected hue to the dress if you're not very careful. DAMHIK!!

    Sorry, I took soooo long getting back, (went camping over the weekend).
    I don't know what thread hijack is?, but I have been trying several thing, to see which I can use best, ( and easyest). Color range, the extract tool. but mostly I just outline it with the polygonal lasso tool.

    It's true I do need a lot more practice shooting with the GS, this was my first time. The set up is with novatron Lights, using silver umbrellas to bounce the light. I am kind of close cause I am only using a 440 power supply and want two light to get a f/11 @ 125 sec with 100asa. Any help in that area would be nice, but that can be a hole nother thread.

    thanks
