Abelardo Morrell is best known for his work with the camera obscura. In order to find new ways to use the technique he worked with his assistant, C.J. Heyliger, to create a light proof tent. This allowed him to project views of the surrounding landscape via periscope style optics, onto the ground inside the tent.
The resultant weirdly weathered images feel that like they were taken long, long ago and have just been unearthed.
