It looks like 3-D films are making a come-back. This year at ShowEast, Dolby's display is rotating around their new 3-D film filter, a rotating wheel which can be installed directly onto a projector.

The wheel splits the projected image into primary colors, and separates the information for right and left eye intake, similar to the red and blue 3-D of the past. However, Dolby's glasses are multi-use lightweight plastic glasses with black frames and passive light-bending lenses.

According to Dolby's informational video, the split images present "not quite identical" images for the right and left eye in respect to their primary color frequencies.

The new technology eliminates the need for costly additional equipment for 3-D projection such as silver screens and active shutter glasses. Provided with the filter itself is a DFC100 Dolby Filter Controller which synchronizes the filter wheel with the content during projection, simplifying the process for projectionists.

The filter is also versatile in terms of use, and can be returned to a 2-D setting for other film projections, eliminating the need for any sort of special set up to project a 3-D film.

With an increasing market for 3-D films, Dolby has begun distributing their filters to major theater franchises country-wide, in preparation for Beowulf, which will premiere not only the first in a line of a new era of 3-D viewing, but the use of Dolby's filter.

Audiences don't even have to worry about showing up early. Dolby assures customers that the side seats and nose bleed section will get just as sharp and clear a 3-D image as anyone else in the theater without having to worry about image distortion or quality loss.

There's no telling how the market will grow for pop-out films now that 3-D technology is available nationally.
