Pseudoscopic illusions in stereo views of freeze-etch replicas

The use of stereo pairs of freeze-etch replicas significantly contributes to the interpretation of spatial relationships of structures within fungal spores. However, great care must be taken to assure proper orientation of prints before publication in order to prevent pseudoscopic illusions (an optical illusion which produces an apparent reversal of surface elevations and depressions). AsHarold C. Conklin [2] pointed out in his letter to Science, this phenomenon is an ever present concern for users of vertical imagery. The sensation of seeing depth in two dimensional photographs is an illusion. The goal is to create the proper illusion.
