    Hey guys, just wondering the best way to pull a nice alpha/matte from a
    greenscreen still shot (from a HD source).

    Magic wand doesn't do the trick for us as I don't think its too clean, let
    alone not getting into to intricate nooks and crannies or transparencies.

    Any help much appreciated.

    Cheers,

    Eamon

    Try the extract command. Excellent once you know how to drive it.

    Extract chews into the image as well. But may be the easiest just look
    up the help in PS to run it.

    Chrome colours are usually a picked colour and deleted.

    It's pretty hard, especially when the background tints the skin and clothing
    with strips of green, in green scene. Even when the images are combined you
    still have that problem to deal with.

    If it isnt white you may as well not use the main image. The fluoro type
    colours are for low resolution video cameras. You cant tell the difference
    in video.

    select colour, delete!

    is the background tinting the subject?
