  Luma Keying sky

  Posted by Daniel Christie on March 20, 2007 at 3:46 am

  Hi,

  I am trying to replace an over exposed white sky with a still. Luma key doesn’t handle the edges of the trees to well. ‘Stencil Luma’ blending mode works well, but turns everythin to greyscale. Any tips?

  Cheers,

  Daniel

  You could try using multiple instances of the Color Key effect. Just apply it, tweak it, apply it again, tweak it, and so on until you get a good key. You could also use Keylight if you have it.

  If stencil luma works well you might try a Luma Track Matte? I don’t think this is ideal by any means, but if it works it works =)
