3D landscapes through a stereoscope
Stereograms are paired pictures taken from slightly different angles, in order to be seen in 3D. Air photos show features we never see from our landbound perspective, and stereo ‘bumps-up’ that information many-fold. A simple, handheld 3D viewer attached to this newsletter gave Discovery members an introduction to ‘stereoscopy.’
