How to View Stereoscopic (3D) Images

Minimal guide on methods to view stereoscopic images, with samples.

This guide for now is minimal, we plan to extensively add to it.
To start, a perhaps overly simplified explanation of the principals of viewing stereoscopic images:

When we view physical objects we are using two eyes, which are separated by about 65 mm. Because of the separation each eye is seeing a different image. Our brain then fuses the two images together, which gives us the sense of depth.

We need to trick our brain by showing each eye a different image, and ensure that each eye only sees the image intended for it.

A very good way to view requires buying a viewer. The Loreo Pixi 3D Viewer is inexpensive and available from Loreo and Berezin.
Better viewers are available from Berezin and other dealers. Ebay and AliBaba and other marketplaces are worth looking at.

Another way of viewing you may be thinking of is the traditional red/cyan Anaglyph glasses.

This works by first processing the left and right image so that one is predominately red and the other cyan. The glasses ensure that each eye sees only one color. The major disadvantage of this is not being able to see true to life color.

To view with proper color, the simplest, but perhaps most difficult way is to free view, where you either cross, or relax your eyes so that each eye is only looking at one of a pair of images. More info on this method is at:

This method is easier when using a cell phone.

For viewing on a computer monitor, an easier method only requires a small mirror, about 5×7 inches. Worth a visit to a dollar store.

We are using a web gallery which lets you change the images for different viewing methods. Click on an image, then click on “Full” to enter full screen. Mirror mode was just added so choose that on the menu which is between “next” and “slide”

Start by centering yourself between the images. Close your Right eye, look at the Left image with your open Left eye. Hold the mirror up to your nose, reflective side facing Right.

Open your Right eye while continuing to look at the Left image. Your Right eye should be seeing the Right image reflected in the mirror. You will have to angle the mirror a bit so that the right and left images are superimposed properly, at which point you should see it in 3D.

You may need to use the “w” and “n” key, or up/down arrows, to change gap between images. Also if keys do not work, there may be a bug with this embedded viewer, the direct link is here

The best way to view is on a 3D TV or monitor.
