Camera Obscura

[P3D George Snowdon <gsnowdon@xxxxxxxxx> To: photo-3d@xxxxxxxxxxxxxxx]

In Digest 1323 Edward Hosey described the Camera Obscura still operating in San Francisco.
There is also one in Edinburgh, on the
street - I forget its name - The Royal Mile? - leading up to the Castle and not far from the Castle. 
It must have been there for about a century. My Dad took me a couple of times when I was a little lad, although we lived a _long_ way away, near Newcastle-on-Tyne in the north of England. The last time I visited was with _my_ daughter, 14 years ago.
It started as a genuine Camera Obscura, the image being focused through a rather large 'pinhole'. But at some point they added a lens to improve the brightness and the sharpness. After all, the skies are usually less bright in Edinburgh than they were in ancient Rome. And the Romans didn't have optical lenses anyway. Or did they?
Like the San Francisco copy, the image is projected from the rooftop down to a circular table, and the view is rotated slowly through 360 degrees.

But it's not stereo. So I digress. Sorry!
