Steroscopic Viewing

[duncanrager]

Greetings,

What are the requirements for stereoscopic viewing with respect to the photography? Can photos be viewed in stereo using any medium, as long as the images are parallel? Would orthorectification make a difference?

I have two old aerial photos from a flight sequence that I can successfully view in stereo... I then printed out updated orthorectified images of the same area on normal computer paper, and had little success extracting elevations and normal features of stereo viewing.

Could anybody explain, please?

Thanks,

DR
