We start by isolating the color channels on each layer. Go to your Layers panel and double-click the “Left-red” layer.Most anaglyph 3D glasses come with red lenses for the left eye and blue or cyan lenses for the right eye. Since the red lens will only let in the red channel, we’ll turn off the green and blue channels for this layer. This can be done under the Advanced Blending dialog.

Since our right eye will only be able to see the green and blue (cyan) channels through the cyan lens, we’ll turn off the red channel for the “Right-cyan” layer With the Move tool selected, press the left and right keys on your keyboard until the two layers are aligned in the middle. I used the model’s face as a reference of where the middle would be.

Anaglyph

Anaglyph 3D is the name given to the stereoscopic 3D effect achieved by means of encoding each eye's image using filters of different (usually chromatically opposite) colors, typically and cyan. Anaglyph 3D pictures can be created in two ways; The first technique combines two separate images from a camera and results in some really cool photographs.This technique requires additional work in Photoshop, but it allows for more control over the final effect. It uses a depth map with Photoshop’s Displace filter to shift the second image out of place and thus creates the 3D effect.

While this technique isn’t exactly like creating a real 3D anaglyph photo because it isn’t using two different photos from 2 different perspectives, we’ve achieved a somewhat similar effect using just one photo.

It’s a simple and easy effect
