    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

    The Ultimatte plugin for Photoshop does an excellent job with color screen
    removal. You can download the demo from www.ultimatte.com and try it with your
    footage on your computer. The demo is full featured in every way, but
    watermarks the output. List price is $495.

    And if you do like it, by a strange coincidence we sell it at a small
    discount, and ship from stock.

    Note that in a feeble attempt to avoid spammers, the return email has an extra
    letter "e" in the screen part.

  3. Eamon,

    There are alot of tricks for getting good selections in Photoshop. A google
    search might yield some. Here's one

    I searched using this criteria: selection photoshop tips

    You might try marqueeing a large chunk, go to the selection menu and choose
    Grow.

    Another thing is to up the tolerance on the Magic Wand.

    Or better yet, use the magic eraser tool, keep on touching it to spots you
    want to disappear to get your alpha channel as you like it.

    Good luck
