To speak about stereo-photo. These internet images are rather disappointing. They have not enough details. All the details of the first image are visible on a slide, at full frame, as this one. Simply watched the pair of slides in simple viewers.
The more there are details, the more the depth is observable. Make your own pairs of stereo slides and you will be amazed. They will be better than these images.
Well, and now, if we looked behind us. Move to the next image.
These images are to be freely viewed, but remain my property. You can use them at your convenience for your private viewing. You are also able to, in the scope of a public or non-commercial presentation, illustrate what seems good to you, and use of these images in any type of media will always be under the condition that credit is given to me with my name either in captions, print or with sound. If your presentation requires paid admission or other financial compensation, you must ask for my authorization.
