stereo camera rigs

anyone know about stereo camera setups? general tips?

just doing a fairly simple 360 path animation of a reconstructed dinosaur skull, a few muscle groups and soft tissue.

The two cameras should be 2.5 inches apart, give or take, for “life size”. If they’re closer together, the skull will look bigger and further away, further apart makes it look smaller and closer.
