If you put 3D glasses in front of a video camera and then take a video of a 3D film, when you play it back, does it look 3D?
(a) No, it just looks 2D, because you need two eyes to see 3D
(b) Yes, it looks 3D, that’s what the glasses do
(c) It looks blurred, because the 3D image is created using two 2D images from slightly different angles (one for each eye) and the camera doesn’t have a brain to combine the two 2D images into one 3D image
(d) It looks blurred, but if you put 3D glasses on to watch it, it looks just normal
(e) It looks blurred, but if you put 3D glasses on to watch it, it looks 3D
(f) It looks 2D, but if you put 3D glasses on to watch it, it looks 3D
(g) or something else that I haven’t thought of…
If you think you know the answer, write a comment and tell me, because I really want to know and you’re not allowed to use video cameras in the cinema, so I can’t do a proper experiment.
