The easiest way to do what you want is to write a simple applescript which does the following:
  • http trigger a preset for each layer to go to full and other to go to zero.
  • a screen capture
  • a launch photoshop with settings command
  • an export to layer 'n' command
  • a loop to chase through each layer
  • a final save photoshop As command


If you don't know about applescript then no worries. If you're curious, applescript is relatively easy to learn and nice to know. There are tons of things it will do to make your life easier with Catalyst.
