Being precise is a worthy goal, but, to my surprise, I discovered that I can get good results with relatively imprecise 3D camera placement.
Before I had a modern 3D camera, I used to just take a couple of photos with my regular camera by dragging the tripod a small distance to the left or right about 7.5cm (3"). The results still looked OK even with small differences with tilt and alignment.
I think this is because our brains also get less than perfect images from our two eyes, but figures things out any way.
I also prefer accuracy, but, based on what I've seen with my experiments, we don't have to worry too much about the lens separation. Our brains already know what we are looking at in a scene and make the appropriate mental adjustments.
From what I learned at the Sony NAB exhibit Tuesday, it's more important to avoid too much difference between left and right views from the foreground to the background. In other words, if you are converged on a close object and the background images are far apart (viewed without glasses), it is difficult to view the image in 3D. Either collapse the distance between the lenses (if possible) or backup from the foreground object.
