a stereoscopic photograph with the two images superimposed and printed in different colors, producing a stereo effect when the photograph is viewed through correspondingly colored filters.
I've recently become fascinated with stereoscopic photography. However, the challenge is displaying the images for others to see. Since red-blue (cyan) glasses are so readily available for viewing anaglyphs, I've posted a some anaglyphs here. Note: your left eye should look through the red lens; your right eye should look through the blue (cyan) lens.
