I have seen a demo of the mentioned Infitec 3x4 band filters and the Infitec splitter at the HighEnd trade show in Munich this May. I was so impressed that I acquired a second JVC DLA-RS50U to accompany my first one. Since the chosen distributor for Germany, who also supported the trade fair demo, didn't respond to my inquiry, I went down the original Dolby 3D path, acquired a few glasses with the 3M lenses and a pair of Dolby 50x50mm calibration filters.
I am still so impressed by the 3D effect, that I didn't care much about calibration so far. Since I already owned a Lumagen Radiance XE-3D, I added a Lumagen Radiance Mini-3D to complete the splitting (each 3D capable Radiance can be set up to only pass on the picture for either the left or the right eye). So the XE-3D drives the left eye the Mini-3D the right one. My pre/pro has two mirrored HDMI outs, so both Radiances automatically receive the same (3D) signal. With the light power of the two projectors, the picture appears to be much brighter than with the JVC shutter glasses.
But above all, I feel, as if I had never seen the real 3D (no pun intended) before. The first generation shutter 3D from JVC (i.e. my DLA-RS50U) produced some depth for me, but the picture never sprang out of the screen. The overall perception was rather flat. The picture was darker, despite the projector running in high lamp mode, and I only could bear wearing the shutter glasses when using some additional nose padding. Even in the movie theater with polarized glasses, I never felt that immersed. I have seen a circular polarization demo with a Runco projector on the HighEnd trade show two years ago and that was impressive as well, but the immersion factor wasn't as high as with the Dolby/Infitec solution.
I am wondering, if it is an individual thing, i.e, if it is due to my very personal way of perceiving things that the color band technology is working so much better for me than the 1. gen JVC shutters or Real3D in the movie theater...?
As far as the need for color calibration with the new 3x4 band Infitec filters goes, I can't really comment on that, based on the demo on the HighEnd trade show.
Once I have found the time, I will try to boost red in the projectors service menu and do the two calibrations for the left and right projector. I have Calman Enthusiast and their C6 colorimeter, but I am not sure, what the best process would be to do the calibration. I could do an Autocalibration with the 125 point CMS, having the calibration filters in front of the projectors. If the color is fine then, i.e. after being projected through the filter, it should be fine as well when watched through the (filter) glasses... what do you think? Is my thinking valid here? Has anybody actually done such a calibration, using Lumagens Radiances?
