Schneider Optics released a set of color-temperature calibration filters for use with projection lenses on film projectors. The filters are designed for digital post-production facilites who need to precisely match the color output of digital and film projectors. The filters can be changed out to compensate for variations in projection, such as those caused by the aging of various elements. The filter holders fit on the front of a standard 70.6mm projection lens, holding the filter at a three-degree angle to prevent reflections. Another kit has a larger-diameter filter holder for larger scope lenses.
