While most hollywood movies like Gravity, Spiderman Homecoming, Justice League are still shot with 2D cameras and later converted to 3D in post production (also called artificial/fake 3D), Shankar's 2.0 has become the first asian movie to be SHOT IN NATIVE 3D ! They have actually used real 3D cameras, the same as those used in Avatar !
The difference will be in the realism of 3D. The artificial 3D which most Hollywood movies use is generated by extracting main-main objects from 2D film and rendering them as 3D objects in post-production; which although gives superb depth effect, but overall, is not how the detail of depth of different things in the whole scene would have been in real.
An Indian 3D movie is coming after a long wait and that too with the most high-end 3D technology which is really exciting! The movie will be releasing on my birthday i.e., 25th January.
