Spitzer image of star formation in RCW49 in 3D

You need to use the defocused eye technique to superimpose these and see this image in 3D. After a few seconds the effect becomes quite stunning. Best viewed full screen.

It seems that, for those who can master the trick, the eye-brain will automatically create a 3D effect from any two images placed side by side which need have only small differences.

Here the right image has been sharpened and the colours enhanced using Photoshop CS3's Lab mode.
