Charles PoyntonI am an independent contractor specializing in the physics, mathematics, and engineering of digital colour (color!) imaging systems, including digital still cameras, digital video, HD (HDTV), digital cinema (D-cinema) and digital intermediate (DI) systems. I am involved in engineering wide colour gamut (wide color gamut/wide gamut color) systems, including xvYCC; I am an expert in colorspaces such as DCI P3 RGB, Adobe RGB, sYCC601, and AdobeYCC601. I do technology forecasting, systems modelling, algorithm development, video signal processing architecture, colour characterization and calibration, image quality assessment, and expert witness work. (More...) It was about 20 years ago that I decided that HD should have square pixels ... I'm a PhD student at Simon Fraser University; my supervisor is Brian Funt. I’m ABD. Allow me to introduce myself, in video. I live in Toronto with my wife Barbara Morris, RMT, CTP Dipl – a psychotherapist. |

Recently, Tue-Wed-Thu, Apr 2-3-4, I presented a webinar, Math and Colour Science for Colourists (ACES). A 1-page flyer (PDF) for the webinar is available. If you missed and you’re interested in a repeat, drop a line. On Sat. Apr. 20, I presented a seminar, Scene-Linear Workflow/ACES, in New York. A 2-page flyer (PDF) is available. I’m hoping to do ACES seminars in LA, Berlin, Munich, Prague, Budapest, and anywhere else that I can find 15 or 20 interested people. If you’re interested – and particularly if you can help me to locate a suitable sponsoring organization in your city – drop a line. Watch poynton.com/w for announcements of additional webinars. The famous HPA Tech Retreat (program organizer, Mark Schubin) took place in or near Palm Springs Calif. the week of Feb. 18~22. I presented a seminar High[er] Frame Rate - Technical Aspects. If several people ask for it, I’ll present it as a webinar! Digital Video and HD Algorithms and Interfaces, Second Edition (Burlington, Mass.: Elsevier/Morgan Kaufmann, 2012), is available at Elsevier, Amazon, and other book retailers. I continue to be flummoxed concerning BT.709/BT.1886 EOCF … |
