The stereoscopic view of the submarine interior above is very similar to the one that revealed the possibility of making paradoxical shadows that float in mid air – the earlier version was a portrait frame but these are landscape and have a sharper floating shadow. Go cross-eyed so that similar elements int he photographs register with each other and then relax until the full three dimensional image resolves itself. Then look just below the periscope handle for the floating shadow.
The top image is of Instrument Six that makes such floating shadows, both photographically and in real time (as shown here, working with candles for a light source).
Some early shots of the Institute for Paradoxical Shadows, before the ground was given a variety of textures.
I have been reshooting Instrument Six – the earlier photographs were too saturated. Here are some tests. The surface on the folding picture plane is a material that retains polarisation, made by Da-Lite Screens. The instrument is seen here in real time mode – to see a shadow floating off the surface on which it should, by rights, land.
Looking through some photographs I found some of the stereoscopic shots I had made of the instruments. Here are a few of Instrument Three.
To view the images in three dimensions, go cross-eyed until you can register one image over the other. You may need to reduce the size of the images a little and perhaps tilt your head a little to keep the horizons together. When you have the image, try to relax to get the full stereoscopic depth.
