It was film based in the past, and film based 3D projection is making a huge comeback.
Two current systems are being offered. Technicolor 3D and Panavision 3D.
Technicolor has over 100 cinema installations in the US, and a few screens in Europe.
Panavision is to be available to theater owners within the coming months.
Basic breakdown:
Technicolor Panavision
-------------- ------------------
Screen Silver White
Film/Digital Film Film with migration to Digital
Film Frame Over/under Over/under
Glasses Polarized Spectral Comb filtering
Glasses cost ~ $1.00, disposable ~ $5.00-7.00, reusable
Business model lease per use not yet determined
Studio support Confirmed in the works
Main obvious difference is that the Tech3D, as claimed by Technicolor is an interim solution, to be in place during the transition to digital. It is a closed solution and in itself provides no transition. Finally, it is inexpensive to get into the cinema, aside from the required silver screen.
Panavision is a system for both today using film projection and possible transition to digital. It is also a system for todays digital projectors. Currently working with Sony projectors, but Barco, Chrystie and other support is upcoming. This places them in competition with RealD 3d, Dolby 3D, XpanD3d.
Technicolor systems looks great. I've yet to see the tests on Panavision 3D.
Film based we get a much smooth picture, with dramatically less flicker than with digital projection. Color is well balanced, and 3d is smooth.
More updates to come...
