Christian 3D: When people see this photo through a 3D stereoscope, the depth goes all the way back to the rear of the tent -- as if you were really looking out over the people. I have been working with early Christian-based 3D stereo view cards from the 1800's. I convert them from their original albumen photography to 3D 4k Ultra-HD digital files. Now they can be exhibited on auto stereoscopic monitors (no 3D glasses needed to see the 3D effect). It is my hope that these new digital files will help take our Christian heritage far into the future. In this photo people assemble under a tent to hear an evangelist on Martha's Vineyard (USA) in the 1800's.
