Classic Parallel Stereoview Pair for 3D Stereoscopic Viewing
stereoview · stereoscopic 3d · side by side image · vintage format
Most Victorian and modern stereoviews are in the parallel-view format, which has the left eye image on the left and the right eye image on the right. To free-view these it is recommended that you look through the stereo pair, as if staring to infinity, and relax your eyes until you can see three images. The image in the middle should be in 3-D and you need to gently bring it into focus, without changing the convergence of your eyes, to see the depth. Composition optimized for a 1:1 aspect ratio.
