I figured I'd share a fun do it yourself project I made. About a decade ago I was working on a project shootin my hometown's downtown area in 3D. I made a very simple low tech rail system to obtain the images on the same plane but spaced apart. Its simplicity was its beauty really: 1 2x2 bar cut down to maybe 2 feet with threaded nut inserted in the center so i could bolt it to my tipod head quick release. 1 piece of angled steel about 6inches long that i mounted to the bottom of the camera. 1 C Clamp to lock the angled steel to the wooden rail if needed. The great part was i could just rest it on the rail for many shots because of shutter speed, and quickly grab images from a variety of distances apart. Since 3D images take a bit experience and trial and error to find the sweet spot based on subject distance. Anyway, it was a fun DYI rig and a real fun project. I'll see if i can find the parts and set it up for a photo if people are curious, I fear the wooden bar used for the rail may be long gone.
