Check these out with the red/blue 3D glasses. Kind of cool, huh?
If you followed my tutorial on how to do this with black and white images, you can probably figure out how to do this.
Basically, the red image is just the red channel of the left image, and the green and blue channels are the green and blue channels of the right image. Combine them using “Add” or “Screen modes”. You can get some eyestraining effects when certain objects are strongly green or red, but overall, the effect works rather nicely.
Give it a try.
Addendum: Others are on the same wavelength as me.
