[3D Roundabout]

By Steve Shaw, Light Illusion

Last time in Part2 of this series, we looked at convergence and the pros and cons of parallel versus converged shooting. I concluded that, all things considered, I prefer the parallel approach in order to avoid keystoning problems and time lost during shooting. This month I will discuss issues concerning the edges of the screen, including edge violations and floating windows.

Conclusion

When viewing stereoscopic images on a small-sized screen, edge violations in negative parallax are something that must be considered, especially to the left and the right of the screen, as they will cause a conflict in the brain between the depth of the object and the screen’s edge. This can be dealt with in post, but can be avoided by using negative parallax effects sparingly, and using it within the centre of the screen.

The floating window can be a useful way to manage issues with objects leaving the screen unevenly and causing stereoscopic failure. …
