How Can We Use 3D Stereoscopy Today?

How Does 3D Technology Work? 

Stereoscopic photography is the area of displaying two separately offset picture as one to give an illusion of depth that gives the picture a 3D appearance. The principle behind stereoscope is called stereopsis. It is just the way our eyes work. We see a single image because our brain makes us see it that way. In reality both human eye capture two different images and set it to the brain. This is because our eyes are few inches apart from each other. Our brain combines both the images despite the spatial difference and makes us see them in a 3D manner.

You can also create a stereoscopic wallpapers collection of your own. It is an exciting fun-filled activity many pursue till date. Stereoscopic photos are not difficult to capture as you can buy the right device at easy today. There is a technique for clicking such images about which you should be well aware.  You need a tripod stand and a camera. Ask your subject to stand right in the center from where you have placed your tripod stand and camera. Click a picture in one position and then shift the camera few inches left or right. Just make sure even after moving the camera the subject is in the center.  These  two separate pictures will help you get a stereoscopic image. 

The best way is to use this method for capturing the image of still objects only. In case you desire to click pictures of moving object some more aids will be required. Either you can use two cameras at the same time or make a mirror splitter. You can find many videos online to see a demonstration of both the methods. There are many different ways of representing such 3D images. We are familiar with the 3D viewing of stereoscopic images using glasses. These glasses have the capability of superimposing the two images as one and give us a 3D view.

Wiggle 3D is a system that allows you to look at 3SD images without the need for glasses. Within  a fraction of a second, the device shifts the picture from left to right. This keeps on repeating in a portion of 0.10 seconds. This gives a 3D effect without the need of wearing glasses. Then there is another method where we can use a mirror to overlap the two images with each other. The cross-eyed process is a straightforward way to display and view 3D images.  The cross-eyed method has a large number of benefits.

You must bear in mind that the cross-eyed way is the only  method that does not make use of any additional tools. The two pictures are placed side by side with the right view on the left side and the left view on the right side. Now the person viewing the image  should cross his or her eyes so that the photographs appear to overlap. However, this is a method not very good for a more prolonged viewing period. Stereoscopes were a great invention more than a hundred years ago. You can make your DIY stereoscope at home. It is easy to make, and you can test the phenomenon of parallel image viewing.
