3rd Dimension

I dabble in stereo-optic photography, which always uses an evil-twin image to create a false sense of dimensionality.  You can see the 3-D effect if you have a stereo viewer (available through Loreo Photography) or if you look at the images really close and then cross your eyes.  The latter method is not recommended. 

I started 3-D photography with a Nimslo camera, a four-lensed gadget that was processed into a reticulated 3-D image.  The photo of the dolphin below was taken with a Nimslo camera, but you can only see the 3-D effect when you have the actual print in your hands. I currently use a Loreo lens cap on my digital SLR to take stereo-optic images like those seen above.
