This file is a stereogram. Stereograms are stereoscopic images or animations which combine left and right frames showing slightly different visual angles to allow for 3D perception.
3D red-cyan glasses are recommended to view this image correctly. |

- Long base line monochrome stereogram anaglyphed for red-cyan filters.
- The viewpoint is from Dinosaur Hill Park above the city of Pleasant Hill, California. The image is of Lime Ridge in the center Shell Ridge to the right, with portions of Mount Diablo in the background.
- A single camera was used to capture two images, the second taken by walking about 100 ft (30 meters) after taking the first. When taking a picture like this it is important that the baseline is at right angles to the distant viewpoint and that the elevations of the cameras are identical. The latter is best achieved by walking along a contour of constant elevation. The two images were converted to grayscale and the left image used for red channel of final image, right image for green and blue channels, although the technique is not restricted to a monchrome production.
- The separation is insufficient to resolve the two peaks of mount diablo (not shown in this image). It appears that that would require at least a 100 meter (330 ft) baseline.
- Leonard G. made this image for the stereoscopy article.
