Une marmotte devant son terrier.

Quick hyper-stereo seems to me, a difficult technique.
I take this image with an 85 mm focal length of recording lenses. The base separation is about 40 cm. I'm at some meter in front of the marmot. I reframe the image when I work on with my computer. So it must be equal to a 170 mm. The depth is exaggerated, but for me it is necessary.
For big wild animals, we take longer focal length. So we are obliged to increase the lens separation. A photographer alone cannot control two distant cameras simultaneously! If he works with an assistant, how can he do the same framing? How can we make a movie with this conditions?
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.
