    Optical Picture Sharpness

    This presentation by John Galt, Senior VP, Panavision Advanced Digital Imaging, and Larry Thorpe, National Marketing Executive, Canon Broadcast & Communication Division, is an expanded version of one that was originally presented at HPA 2008.  This was a response to an industry wide plea for a singular method of comparative evaluation for the effective picture sharpness of high-resolution lens camera systems that employ both different image format sizes and sensor technologies.  It was intended to spur an industry discussion on this important topic.

    John Galt and Larry Thorpe, present their views on a realistic, scientifically valid way to gauge the quality of recorded pictures that belies the theory that “it’s all about the pixels.”

    John Galt, Head of Advanced Digital Imaging at Panavision, and Larry Thorpe, National Marketing Manager at Canon Broadcast & Communications Division (USA), came together to help untangle some common misunderstandings in Digital Camera Specifications.  The sessions were held at the Panavision global headquarters in Woodland Hills, California.  John holds several U.S, British, and Japanese patents in film and electronic imaging related areas.

    This seven part series will be presented in three resolutions:
