Double exposure using channels – How to ?
Hey all
Im trying to create this effect that i am able to achieve in Photoshop using some actions.
It utilizes the channel mixer and the Hi-pass filter to be able to control the blending.
Any suggestions on how i could achieve this in After effects ? or if there exists a plugin that does something similar ?
thank you !

There’s a channel mixer effect in AE. Have you tried working with it?

For this particular case you dont need to mess with the channels at all. As far as I can tell this example does not use the corresponding channels in a true fashion, because (for example) the red layer does not seem to have a background. The easiest way to achieve this
– Put both videos/images on top of one another
– Add a Levels or Curves effect to both of them but do nothing yet
– Add a Tritonus to both of them. Turn the Highlight s and Midtones on both layers to white and the shadows to Red and Cyan respectively
– Mess with the Levels/Curves until you see the details of the image you want to show
– Set the blend mode for the top layer to multiply
