 2D plus depth processing can be used to recreate 3D scenes even from a single view and convert legacy film and video material to a 3D look, though a convincing effect is harder to achieve and the resulting image will likely look like a cardboard miniature.Production of events such as live sports broadcasts in 3D differs from the methods used for 2D broadcasting.A high technical standard must be maintained because any mismatch in color, alignment, or focus between two cameras may destroy the 3D effect or produce discomfort in the viewer.
