The principles of stereoscopy have been utilized as a means of visualizing solid forms since the 1830s. Photographic stereoscopy grew simultaneously with the growth of photography and had its heyday in the 1950s and 1960s. Cameras and viewers and are still made, but it's also possible to create stereo pairs with a single camera, digital or film. This type of photograpy still attracts new and enthusiastic practitioners, so there are many resources available.

The pages below feature both photograpic stereo pairs and 3D renders in the "cross eyed" viewing format. If you are unfamiliar with this viewing technique, I suggest you read the instructions here.

Karlovasi, Samos, Greece - 2001
The stereos of Karlovasi were taken on the island of Samos in Greece in 2001 (with the camera above). The series begins with views across the town, then down into the old town and finally the tanneries on the Aegean Sea. 10 images - 650 x 365 pixels.

Sydney Harbour - 1960?
These Sydney 1960 stereos were packed with a viewer I bought at the local markets. Unfortunately I don't know the photographer's name. These were taken around Sydney Harbour Bridge and Circular Quay well before the Sydney Opera House was built. The panoramic views were taken from the Harbour Bridge pylons. The view with the ship in the backgound is now a pedestrian walkway to the Opera House. There's also a nice shot of Luna Park. 5 images - 650 x 365 pixels.
