Stereograms - 'See' the 3D objects using Photoshop
How to make your own Stereogram - 3D Object Viewer using Photoshop!
Video tutorial steps:
1) Load stereogram image in Photoshop
2) Duplicate the stereogram layer
3) Define a 2x2 pixel chequerboard pattern with black and transparent pixels.
4) Create a new empty layer above the two stereogram layers
5) Fill this empty layer with the chequerboard pattern
6) Select all black pixels on this pattern
7) Select the duplicated layer and press delete. (This has now removed every second pixel from this layer (see-through).
8) Deslect all.
8) Move the duplicated layer across the image (hold shift) until matching elements converge. The 3D object will appear for a split second.
9) The layer has to be moved continously across the image to see the effect. Once movement ceases all depth queues disappear.
