The Kodak Cross-Step Gray-Scale Slide for Telecine

Daan M. Zwick

There is a need by television broadcasters for an operational gray-scale slide which is stable, achromatic, non-scattering and of known transmission values. This slide should be used at the field lens position of a mutliplexed telecine to permit color balancing and shading operations with each of the multi-projector inputs, and to allow tracking and gamma adjustments of the camera. Conventional silver and dye image slides do not satisfy these requirements. A new test slide, made made from a metal alloy evaporated on glass, has been designed and constructed for this purpose. Experience with this slide has shown it to perform as intended in a variety of telecine equipments.
