| STEREO VIEWING METHODS are
numerous and changing. All methods require a source stereo pair that
is converted for viewing. This conversion is best done by the end
user and not the content generator (allowing more of us to post with less
hassel). End users need software that recognizes the specially named
files and opens them on demand. The image file is a JPEG (or JPG)
image with the right image saved on the left side. Any JPEG having
the RIGHT IMAGE IS ON THE LEFT can be opened using any good 3D viewing
software. Such images are usually renamed to have a file extension
of JPS (.jps) to engage the viewing software. Good viewing
software will open the JPS pair and convert it to your preferred viewing
method.

This page shows digital images that are already converted to allow side by side comparison. The purple peppers were found in Arcata California's farmers market one Saturday morning in November 2001 using a single Kodak DC 240. |

| Parallel viewing allows 2.5" between image centers before going "walleyed" (eyes divergent). This view is 3.5" and is suited for a viewer with wedge. This viewing method does not uses all of the pixels available on your monitor. (unless you use a .pokescope viewer) |
Color Anaglyph Some color problems

Gray Anaglyph images are effectively B&W
stereo anaglyph. All of the image color is gone and a reasonably
good B&W show good stereo.

| By cleverly merging the gray and color anaglyph
one can get a suggestion of color. Color channels can be used and
time spent - but this image is not well suited for anaglyph because of
too much red. Agreat color anaglyph
usually requires careful subject selection, technique, or luck.

| Interlaced pairs are used for shuttered glasses. Every other line is used for the left image while the right shutter is closed. The right image also uses alternate lines. This image is compressed to 200K shows slight problems with image crosstalk due to the compression. It is better to interlace from separated images (JPS pairs) for superior image quality. The full color viewing does justice to this subject but the blocky compression is marginal. |
| Web compressed and sized jpg 20% These images don't crosstalk because they are stored side by side. These are "full sized pairs" where each image will fill a 17" monitor. You have to convert an image like this using software. |
| This 90% jpg 665K image is only slightly compressed for burning to CD. These are very slow to load and take up too much web site space. This sort of image makes the best use of today's hardware with a image size of 1150 x 900 pixels x 2. If one were using twin projectors with polarizers this would project very well Or you could use twin monitors or a viewer that requires no glasses. |
