Just bought the harry potter deathly hallows part 2 on 3D blue ray. Its whats called fake 3D. Its filmed in 2D and converted to 3D. Some fake 3D films look good and u get a feel of being there. But the harry potter film does not have any 3D in it all. I think 3D films should say on the box what type of 3D it is as some r better than others. IE true is proper 3D filmed using a 3D camera. Real 3D is better known as fake 3D its filmed using a standard 2D camera and converted later. SBS is side by side Which is 2x 2D cameras mounted side by side and looks good if u have the active glasses. and annoglyph which u can watch on any tv using the red/blue lense glasses.
