  Expression Brightness Value

  Posted by David Womack on December 14, 2005 at 5:46 pm

  I’m trying to tie the brightness value of a tga sequence to the intensity value of a light. can anyone help point me in the direction of determining the brightness value of a pixel or specific section of an image??

  Thanks!

  You need third-party plugins, namely a color sampler. Try Digital Anarchy’s Arnachy Toolbox or look for Useful Things or Bresnev Shu’s Expression Effects, the latter two being hard to come buy since not longer easily available.
