You may have noticed people peering through what looks like a pair of small binoculars in the photos from Rob’s last lecture. This is a stereoscope, a devise for seeing specially prepared photos taken with a two lens camera. The two lenses of the camera combined with the viewer allow you to see the photos in real 3D! Popular in the early 1900s, this seemed an ideal medium to showcase our historic equipment. Inspired by Diego Ruiz, Rob created a series of his own stereo photos. If you have your own stereo viewer, you can take a look at the photos below, or come to Rob’s next lecture to see them all.
