Many years ago when I was a little tacker, my grandfather got me interested in photography.

He was a Chemist by profession, but was an inventer and engineer as well. Even in his 80's he was going to night school on his quest of knowledge.

Anyway back to the topic, be had a large collection of Exacta Cameras and Lenses and I have some of his photos but none of his gear, unfortunately.

One of the interesting things he made on his lathe was a 2 mirrored reflector that screwed into the thread of his lenses. Each outlet was about 6 inches apart and this would give 2 side by side images on a single 35mm slide.

He also made a viewer which started life as binoculars that the slides where viewed through.

The image produced was true sterophonic with depth and 3D imagery.

These items are lost as well.

I have never seen anything since, nor found anything on the internet.

Does anyone else have any knowledge of this form of photography?

Sensational, how does he do it?

2 Cameras or 1 Camera with mirrored devider?

He will tell you how he does it but I think you will find he does it from a SINGLE Image :D .... Skippy

Nope I take that back .... I just found one of Brians threads about STEREO Images here you go have a look
through this thread .... Skippy

Hi, I've been playing with 3-D images for a while.
There are several ways of doing them- 2 cameras with the shutters linked on a platform, a loreo 3-D lens cap fitting or as I do them, the cha-cha method- One camera- take one shot, move the camera sideways take another shot. The movement should be about 1/30th of the nearest subject distance from the focal plane, so for macro shots this may be as little as 5mm.
There are 3 main types of stereo pics.
1. parallel pairs- two shots positioned as taken- viewed by staring through them (like those magic eye things from a few years ago) or using a stereo viewer - bit like binoculars to isolate the images going to each other.

2. Cross-eye pairs- these are the type I do. same as parallel pairs but the images are swapped over and you go cross-eyed to view them.
Full method- These can be viewed as is by slightly de-fcusing your eyes, stare at the pair of pics and cross your eyes unti a third image appears in the middle, then try to relax your eyes so your brain can lock the 3-D image. If it doesn't work at first don't try too many times as you can give yourself a headache- try again later.

3. Anaglyph method- here the shots are colour filtered, overlaid on each other and viewed with those red/blue colour filter glasses.

I use some freeware software, stereophotomaker to help align the shots and produce the finished shot pair.

It's great fun doing and viewing 3-D images and there's lots of info on the Net if you search for it.

Thanks, its alot like looking at those 3D computer generating posters that got around about 10 years ago, but much better.

I thought it was a forgotten aspect of the creativeness of photography of yesteryear.
