Stereoscopy: Anaglyphs

1. National Geographic Magazine: 1998 article on the Mars Rover.
2. Walking with Dinosaurs, 3D version: a large book for children currently on sale in local book shops. (It is actually too good for children).

Separation of the two channels is not great with red/blue-green glasses.

Grey anaglyphs are recommended.

Colour anaglyphs are also possible. The colours look good without the glasses but through red/ blue-green glasses they are not convincing for every body. In particular red does not come out well. (Some people  prefer the colour version - it is all in the mind).
