Weird Photos Shot By My Grandfather

By John Potter

Among many other things my grandfather and I held in common is a love of Florida and a desire to experiment with photography.
I wanted to share this group of photos my grandfather shot from around 1948. Many are shot in Florida, although he lived in Rhode Island.

There are two types of photo here. One is simply a wide format which he mislabeled as sterescopic. The rest are sterescopic. Now sterescopic photos have been around about since photography was invented, but what my grandfather created were specifically called anaglyphs and used two images shot at about the same distance apart as human eyes and then recombined using a viewer. Kind of like the View-Master you had as a kid (if you’re as old as me). Anaglyphs were very popular from about 1850 to the 1920s. Apparently my grandfather decided to try his hand at it in the 1940s.

Using the anaglyph viewer

I cannot reproduce the effect of viewing through the anaglyph viewer literally, so what I have done is create little two frame animations out of the two frames. Each frame displays for point one second giving you an idea of the three D effect. They aren’t all great, but a good effort considering I’m relatively sure he had no proper equipment. How he shot the ones of himself must have been an interesting story. If he didn’t have someone else move the camera and re-shoot he had to use some type of mechanical device.

Use Panoramic Photos For Research

By John Potter

Panorama locations in Google Earth

A little while back I began maintaining a Google Earth file pinpointing the locations of most of the panoramic photos I’ve shot. Since most are clustered in southeast Florida, north central Florida and upstate South Carolina this file could be a handy tool for anyone planning on visiting these areas. It gives you a more realistic idea of where things are in relation to one another while still keeping that “feet on the ground” type of perspective.

All you need to do is open the KMZ file I’ve created for you directly in Google Earth or download it and open it from your computer.
