Viewing Stereo Photographs
Many of us are familiar with stereo photography. Remember the stereo viewers grandma had, or the toys that showed 3D images of cartoon characters.
We see the world in 3D naturally, so why should we view photographs in only two dimensions? It can be done without any optical devices or funny glasses.
Our eyes, because of their location on our face, are looking at objects from two perspectives. Our brain processes the information from each eye and makes us see them as one.
To get 3D photographs, two different images are taken with some degree of separation. It has to be done technically correct and then processed with precision. The next step is to view them properly so our brain can process them into a single image. We then see that dramatic and wonderful stereo view. Now you can enjoy the full depth that I witnessed as I captured the photographs.
Viewing these images without optical aids is called “freeviewing.” It can be learned and the more you do it, the easier it gets.
Many have seen books that do this, but this is much better because what you see in front of you is what actually becomes 3D. It simply goes from grand to great. We are NOT looking for hidden images, just a stereo version of the art in front of us. So don’t give up! If your eyes get tired, take a break. Your eyes and brain are not used to this, but it is worth it and you can do it!
There are two main methods of viewing: crossed and parallel. However, my fine art prints are so large that crossed tends to be the only method that works. For small images like greeting cards and stereoscope cards, either method will work. One may work better for you than the other when viewing small pieces. All my 3D prints are made to be viewed via the crossed method.
