First thing i did was selected an image that i wanted to edit and dragged it on you photoshop.

 Then i duplicated the layer so that i could change the levels on each layer. I choose the background copy to edit first.

 I selected the levels ...

 i changes the levels so that they were both on 0

 i also did this for the green and blue.

 then i changed it from normal to screen

 then to make it 3D you have to move the top image to the right and down and it will then look the the image above

 then to get rid of the red edge i simply croped it.

this is my final image to see if it has worked i used the glasses.
