Nobody has compared the VIDEO/MOVIE market to the PHOTO market looking at the evolution and take-up of 3D Photography (which remains a niche and curiosity market). 3D Pictures were available to the Victorians and 3D photography has been available in the market ever since – However I do not see 3D Photos being demanded by the  industry or 3D Picture Frames or 3D albums or 3D graphics novels … Why is that?   Probably because it is not the way the brain was intended to view…Perhaps it is because we have sight that functions very, very well, those blessed with it.   Now that we have high resolution graphics it is possibly enough for the eyes.  Yes we have sight that is deemed OK except that 3D TV is trying to rearrange it?
