Color separation in Photoshop

How to separate an image so you can do trippy color-separation effects to it.

Before After

   

1-Click on your Layer window.

2-Make a new layer, name it Red.

3-Locate the Channels Tab (usually under Layers) or go to Window/Channels to bring it up.

  

4-In the Channels window, click on Red. The other eyeballs should be off.

5-You’ll see a black-and-white representation of your image. White is where that color is fully present, Black is for absence of that color, grey is for in-between values of semi-Redness.

6-Cmd-click the Red thumbnail to load it as a selection.

7-Back to Layer window.

8-Edit/Fill. Use Color, and make red value 255.

     

9-Red is 255 as below.

10-Turn off eyeball on Red layer.

11-Repeat steps 2-9 for Blue and Green

12-Turn on your Red Green Blue layer eyeballs again. Turn off your original layer eyeball.

Image should look creepy as in the below.

   

13-Make a new layer, fill it Black. Image continues to look creepy.

   

14-Select your color layers. Set their blending mode from Normal to Linear Dodge (Add).      

15-Image back to normal...Or is it?
