Stereo Imagery by Richard Grotjahn

This File Under Construction

Welcome to my stereo page. I hope you enjoy the images displayed here and find the discussion of how to view stereo helpful. Please note that all the images presented here are copyrighted to me, Richard Grotjahn.

This file is divided into two parts. In the first part are some examples of "relaxed eye" stereo pairs. (i.e. you do not cross your eyes). This is followed by links to pages with more examples. The background and some other non-essential aesthetic items were designed to be viewed using Netscape viewers. However, the stereo effect should be apparent on other viewers. One detail may be to ensure that your window is wide enough to see the images side-by-side.

Stereo pairs can be made from "movies" if the object is panned across the screen. To illustrate the idea, I have also included a link to my "Snappy" stereo images (made from ordinary video output). I recognize that these images are poor quality; the intention is to illustrate the concept.

This is followed by a tutorial that includes: tips on making stereo images using computer graphics or by using a regular camera. Also presented are tips on projecting the images. Finally, I have a tutorial on seeing the stereo effect without a viewer.

These stereo pages are also available as a mirror site located in Italy. This site is courtesy of Paolo Mattesu.

Examples of Stereos

The images here are grouped in pairs that should be displayed side by side. If your viewer has placed one image above the other, try making the window of your browser a little wider so that each pair is displayed side by side. I have used small sizes to facilitate the side-by-side viewing as well as to keep the total file size manageable. However, some images reproduce better using small size than to others.

Frontal Zones

The white "cloud" is a cold front (over the southeast) a warm front (over the Atlantic) and an "occluded" front (over New England). The gold "tube" is the jet stream. Contours are of sea level pressure (8 mb interval).

Why 3 images?
The images are, from left to right: Left eye, Right eye, Left eye. For 'relaxed eye' viewing use the left & middle image. For 'crossed eye' viewing use the middle & right.

Cloud Photos

Stereo images of cumuls congestus along a cumulus street (Sweden):

Images of cap cloud (Mt Hood, US):

Rotor cloud created in lee side upslope of mountain (New Zealand):

Unusual Effects

Stereo of a reflection in a lake (New Zealand):

Stereo of a rainbow (Davis, California):


Since both views see a different 'object' defined by light from the sun, one might expect the rainbow to be far away. Instead it looks somewhat 'deep' with a background cloud clearly behind it. The apparent 'correct' 3-D image is due to using a tree in the forground as the aiming point.

More stereo images

For more stereo images, I have set up a couple of other pages. They are grouped by general subject. Each group listed below consists of about a dozen PAIRS of images. Each image has from 13 to 54 k bytes. Most are under 20 kb. As with the images above, they are small in size to keep the total file size small.

• Desert scenes
• Flower scenes (These have some of the most striking 3-D effect)
• Mountain scenes (for these you have the option of "relaxed eye" or "crossed eye" viewing)
• Miscellaneous scenes (also with the option of "relaxed eye" or "crossed eye" viewing)
• Miscellaneous scenes

• Weather scenes (more cloud stereos)
• Computer-drawn weather data (some stereo images drawn by a computer)
• Weather scenes (even more cloud stereos including mammatus and wave clouds (mainly from Chile). For these you have the option of "relaxed eye" or "crossed eye") NEW
