LATEST ADDITIONS

Video guru Joe Kane was demonstrating the Samsung SP-A800B projector that he helped design (review forthcoming), but it wasn't on a Stewart screen as usual. Instead, he was using a new screen material he developed with Da-Lite. Dubbed JKP Affinity (JKP = Joe Kane Productions), the new material is exceedingly flat with no diffusing granules as on many types of projection screens. This is said to improve flat-field uniformity and depth of modulation by reducing light scatter, leading to greater detail and contrast because adjacent areas of the image don't interfere with each other. The current material has a gain of 0.9 and should be available in a few weeks. The demo was impressive indeed, with exceptional detail and uniformity; can't wait to shine my light on one.

One of the big themes are CEDIA this year was 3D, and Da-Lite was in the thick of it with a new screen material called 3D Virtual Grey (though I would have used the American spelling "Gray"). Designed for 3D applications, the material is said to retain 99% of the incident light's polarization, which is the key to achieving a good 3D effect using polarized light and passive glasses. The demo looked quite good, smoother than most I've seen, which could be due in part to the fact that the real-life material was shot stereoscopically with two cameras and the CGI was created specifically for 3D.
