projecting a colourful 3D display

Viewing in 3D dual transparencies projected in colour – one view for each eye. in colour

Toronto. This article appeared in the September, 1940 issue of Popular Mechanics just a few years after Kodachrome arrived for 35mm transparencies created by an ordinary 35mm camera. Now these slides could be taken ready for 3D and projected so a room of people could experience the slides at once.

We in the PHSC thought nothing about using polaroid glasses in cardboard frames to view 3D slides presented by members Stan White or Paul Pasquarello. But in 1940 they were very special since prior to that time slides were black and white, or drawings viewed by one person at a time with a special hand-held viewer.

A thank you to my good friend and photo history researcher for sharing this article with us.
