  invert intersection of 2 black objects

  Posted by Katherine Landgrebe on October 27, 2009 at 7:42 pm

  Maybe it’s easy, but I can’t find the right way to get the intersecting parts of two black objects white. It works with the Difference Blending Mode, but only if I change the black color of the layers to white and put another white layer in the background. This would mean a lot of work for all the objects I want to be inverted when black meets black. Is there a quicker way?

  How about finishing the animation and precomp top? half, dupe it and make bottom white
  then use the blending mode?
  -K

  Reality? What did you make it?

  Hi Keith, sorry I saw your post only now. Thanks for your response. I’m not exactly sure what it means. But I figured out that there is an invert channel effect. This could work with an adjustment layer in each comp, I guess. Maybe not, because it influences the white parts as well. Anyway, it seems that I won’t get around some detail work. I’ll keep on trying 🙂
