I took a stereo photo of our cat kissing our dog and made a 3D printed relief photo from the left and right images.
Shapeways.com 3D printed the stereo photo model in color sandstone. See

The 3D relief photo measures 3.5 x 2 inches and .5 inch thick at the highest point on the right side (photo above).
To construct the 3D print model I used PhotoSculpt Textures 2 software. Check out
