Putting the fun back into cinema To find out what is important to exhibitors in the 3D discussion and which issues they feel should be improved, we spoke to four European exhibitors, running cinemas ranging from large multiplexes to smaller complexes All of them had recently reconsidered their initial investment and were therefore well informed about the current 3D systems and the choices that need to be... noticeable the more the image extends into the negative Z plane, when the image appears to come right out of the screen into the auditorium The three dimensions of 3D are termed, X, Y and Z X and Y are the usual two dimensions, Z being the third dimension, depth Positive Z is going back into the screen, negative Z is coming out of the screen Some 3D systems suffer more from ghosting than others and... films we bought the system at the beginning of 2010." A fair share Although there has been much talk about the different 3D projection systems, the main 3D discussion in the past year focused on the surcharge that exhibitors charge the audience to pay for their equipment Distributors demand their share, as they argue that they make extra costs as well, because 3D films are more expensive to make than... alongside the 3D and in ambient light conditions The 3D display was very bright and very clear Compare this with a cinema 3D experience and 16 3D Cinema Technologies there may come a time when the public will ask, “Why is 3D at the cinema so dull?” Currently, they are still bowled over by the experience, it’s all new and they have nothing to compare it with Give it a couple of years when Sky’s 3D channel... lenses to the screen Each half of the 4k image contains one 2k image This allows the parallel projection of the left and right eye image With this method a significant reduction of flickering is possible The screen and the glasses are the same as with the RealD system Dual projector system The dual projector system works in the same way like the Sony 3D system The only difference is that the source of the. .. 4k projector but two 2k projectors The projectors have to be synchronised to each other and the player has to feed both projectors The main advantage of this method is the higher available light output Conclusion 3D projection systems within digital cinema could eliminate some significant weak points of older 3D systems Digital pro- Fig 9 jectors have no judder, with the use of only one projector an .
