Convert a flat image into a 3D stereo image.

Use the "Displace" filter to create a stereo image from a flat image. The displace filter will move pixels in response to a separate grey scale image. You need to create this "depth map". You can do this by painting on a layer on top of your image, using your image as a reference. The more care and detail you put into your depth map, the better the 3D image will be. You can also use false depth. For example, you can use luminance as depth. Just copy a channel and save it as a depth map. Great for abstracts. Be creative.

I get something that I'll have a hard time explaining in both english and my home language. Let's say I have a painting of a person and they sky behind him. If I make the person black and the sky white in the displacement map then I see parts of the person floating in the sky on his right side and missing parts on his left side.

@ShinzuiUindo

Try splitting the displacement between the Left and the Right images.

Make the sky 50% grey (126 = No displacement)

Make the person about 25% grey (R=G=B=64)

Make two copies of your image

Apply the displace filter with a horizontal scale of, say 5, to one copy.

Apply the displace filter with a horizontal scale of -5 to the other copy.

Use these two images as your stereo pair.

how did you  put the images side by side

[TomS3D]

@tdivv41 I have written macros for the common tasks I use in manipulating 3D images. So I only need to hit one key to expand the canvas 200% and move the top layer image next to the bottom layer image and flatten to make one side by side image. It's also handy to have a macro to do the opposite, and take a side by side image and convert it to two layers, and also a macro to flip the left and right half of an image.

Awesome tutorial man, just what I've been looking for.

THANKS A LOT MAN! aaaaaweeesome :)

isn't it usually white to black?

[DutchBlackMantha]

@ShinzuiUindo The base problem is that the displace filter does "new(x,y) = old(x + map(x,y) , y)", while you want "new(x + map(x,y), y) = old(x,y)"; the latter moves the pixels by their associated displacement value, the first associates the displacement value with that pixel on the NEW image. The problem with doing the latter is that some pixels would need to have two or more values, while others would be undefined, so it's no surprise Photoshop doesn't have the option.

I just did this with a painting and put it on my 3DS!

A good tip for anyone trying this is to spend some time blending the different layers with the smudge tool to get a smooth looking result

Thanks for the tutorial
