When shooting with a 3D rig, the eye that is not captured through the half-silvered mirror is usually sharper and has fewer artifacts than the other eye. This is the hero eye.
In the GS film world, a film is divided into three-minute rolls and the hero eye is normally made up of the best rolls from either the left or right eyes of the overall film.
In the digital world, the hero eye can be chosen shot by shot, according to time and budget available.
