A group of quite old pictures of Instrument Six in stereo. THere is quite a lot going on so the 3D view clarifies them. The top view is of the instrument in photographic mode with a single bulb as a light source while the lower two are of the instrument in real-time mode where you can see the floating shadow directly. For those new to the blog, Instrument Six is able to separate an objects shadow from the surface on which it should land and get the shadow to float in mid air. It is explained in earlier posts, for instance here and here.

Use the normal process for resolving the stereo images.

Three views of Instrument Six in action, the two top views construct paradoxical shadows that float in the air, adjacent to  the surface you would expect them to land on , in real time. The bottom image  is of the instrument in photographic mode where the relative parallax between shadow projections can be adjusted for pairs of stereoscopic photographs, and it uses a single lightbulb instead of a pair of candles.

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.

Design Ecologies

I just received a copy of Design Ecologies (Volume 2 No.1) edited by Shaun Murray. The title of the issue is The Ill Defined Niche. It has chapters by Shaun Murray, Camila Sotomayor, Tim Matts and Aiden Tynan and one by me called Drawing Uncertainty that covers some of the instruments and the Bird Automata Test Track. If you are interested you can order a copy here.
