I was not aware that so much could be done with Film.

I learned the other Day that British intelligence during WW2 could produce 3D type images from ariel shots and this was old technology taken from the Victorian era!!

It was routine to take two shots one after the other as the survey plane flew over the territory. These were then viewed as a stereo pair.

I have a nice stereo viewer designed for this purpose. It would be used with prints about 10x8 inch.

Stereo photography as such dates right back to the earliest days of photography around the mid 19C. Stereo Daguerrotypes were common.

Then at the end of the 19C, Ives developed an elegant system of colour stereo photography using colour separations. Each photo was made up of six images - left and right in red, green and blue. Google Kromskop for details.
