What are Stereoscopic or 3D images?
We see the world with our two eyes. Each eye sees objects from a slightly different
angle, therefore the eyes send two different pictures to our brain. Our brain then overlaps and analyzes the two images, producing the visual sensation of a single 3D image! This is what is known as
Stereoscopic phenomena.
3D photos are presented as pairs of images that were captured using lenses separated by 6-7 cm. When you allow each eye to look at only the image on its corresponding
side, each eye will perceive a single view from slightly different angles. It is then that you will see the magic of 3D pictures. The image will appear to have depth and the scene looks alive! At
first you will need some practice to let your eyes overlap or fuse the two stereoscopic pictures ( Free viewing ). Why triplet pictures? Shouldn't there only be two?
Yes, it must be only one pair of images, one for the left eye & one for the right eye. I will explain that later. When looking at a triplet picture, the far right element is the exact
same picture as the far left element. When looking at the triplet from left to right, you will find the images are in this order: Left-view / Right-view / Left-view. How would we see your images in 3D?
Stereoscopic viewing of these images requires concentration and may take some patience to master. If you are not successful after five minutes, try again after a few moments. Most
people need a little time and practice, but once you do it you will remember it forever! For your first attempt, choose one triplet from my preview pictures, I recommend Make Love, but any one would be OK. Look at a triplet
picture, but ignore the far right element for now. Sit in front of your Monitor and stare at the picture for a while. With your eyes relaxed, overlap and fuse the first two elements one upon another.
While focusing on the pictures, allow your eyes to relax so that you begin to see a double image. This simply means that your eyes should no longer be converging on the monitor, but instead are
looking parallel with each other, as if looking at a distant horizon. If you succeed, you will see three pictures instead two! You have then succeeded to overlap two pictures, the middle one will be
clear & sharp albeit in 3D !
If you can see the 3D picture clearly using the method described above, it means that your left eye is only seeing the left element and your right eye is only
seeing the right element. This method of 3D viewing is called Parallel viewing. For some people, it would be easier if their left eye sees the right element and their right eye sees the left element.
That method is called Cross viewing. For Cross viewing, one should ignore the far left element from my triplet pictures and only stare at the middle and far right elements. Your focus
should remain on the screen and the pictures should not appear blurred. Your head MUST be level with the picture for the effect to work. When the two pictures have become merged the
brain will register the images as it would in reality, and the stereoscopic effect should pop into your view.
Depth should become very apparent in the pictures and a surprising amount of detail should be seen. Good luck, Shahrokh Dabiri.
