  Channel > Set Matte takes too much

  Posted by __peter__ on September 12, 2005 at 5:57 pm

  Hi 🙂

  When I am using the Channel > Set Matte function to do things like the lightspill from John Starr Dewar’s tutorial, I notice, that the resulting Matte is not exactly like it was before. It clips more pixels around the edges than it should. I thought of a pre/unpremultiply-problem but I cannot fix it.

  Does someone know the problem ?
  So what to do about it ?

  Thanks for every idea!
