Abstract: With the growing popularity of digital intermediate in the feature film market and the continuing development of improved telecine technologies for television, the notion of traditional camera origination film design optimized around direct optical or contact printing is radically challenged. For scan-only film image capture systems where the camera film will be scanned exclusively to video or data and never directly printed, a very different approach is taken to sensitometric curve design. Rather than focusing on tonal characteristics, which yield acceptable and preferred results for overall contrast, grayscale neutrality, and shadow and highlight detail in a traditional printing paradigm, the film curves must instead be drawn to optimize the quality of signal provided to the digitization step in the film scanner. Further, standard constructs of color reproduction are also open for modification as the film's spectral sensitivity and color-enhancing chemistries are changed to better mesh with digital color-processing capabilities.

bio
David Long joined Eastman Kodak Co. in 1997 as a member of the Manufacturing Research and Engineering Organization. In 1998 he moved into his current role as product development engineer and hybrid imaging scientist with the Entertainment Imaging Division. His primary responsibilities with Kodak include new product development and image science and systems integration for the motion picture group, focusing on film and hybrid imaging products. Long joined Kodak after graduating from the University of Texas at Austin with a BS in chemical engineering and from the University of Rochester where he earned a MS in materials science.

Tom Maier is a research fellow in the Entertainment Imaging Business Unit of Kodak. During his 33-year career at Kodak, Maier has written computer programs to model film and digital imaging systems, developed methods to characterize and optimize the color quality of these imaging systems, and has run psychometric experiments to confirm the image-quality of his computer optimizations. Maier has served on a number of the CIE committees related to color, as well as several SMPTE DC28 Standards Committees for Digital Projection Systems. He earned a BS degree in chemical engineering from MIT and a PhD degree in chemistry from the University of Illinois. He is a member of SMPTE.
