This technique will produce potentially significant rendering artifacts in the final image. The backdrop is correct only from the position of the camera. A reflection from any surface will not be geometrically correct (as seen by the image from the article) I think that even ambient lighting would contain noticable deformations.

It's much better than the reflection of a green/blue screen or an empty studio with some cameras and people.

Glossy surfaces are usually not a problem unless they're (near) perfect mirrors. Even then -- lights are usually what you see in most reflections because they're orders of magnitude brighter than the rest of the set.

If reflections are problem with this new technique in certain settings, they would be even more with the current state of the art.

In those cases you replace them digitally. No way around this; either way.

Related trivia: The chrome starships in EP1 were actually rendered with environment mapping and reflection occlusion[1]. Even most games do better stuff today. Did you notice? :]

Right but the artifacts here will still show up on glossy surfaces. Here is how games now fix these kinds of artifacts. https://seblagarde.wordpress.com/2012/09/29/image-based-ligh...

However the technology in the article cannot be corrected in this manner.
