Charles Poynton, PhD
I am an independent contractor specializing in the physics, mathematics, engineering, and programming of digital colour (color!) imaging systems, including digital video, HD/UHD/4K/8K (HDTV/UHDTV), VFX/CGI, and DI and digital cinema (D-cinema) systems. I am involved in engineering wide colour gamut (WCG, or wide gamut color) and high dynamic range (HDR) systems. I am an expert in colorspaces such as BT.709/BT.1886, DCI P3 RGB, Adobe RGB 1998, ACES AP0/AP1, and BT.2020. 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 25 years ago that I decided that HD should have 1080 image rows, and square pixels ...

In 2019, I presented a webinar, Math and Colour Science for Colourists (ACES). It’s a mathematical take. If you’re interested in experiencing that, drop a line.
I’m hoping to do ACES seminars in Prague and/or Budapest. (I’ll do it 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.
I was, a decade ago, flummoxed concerning BT.709/BT.1886 EOCF …
Subject to my main gigs in olour and image science, if you have an interesting math problem maybe I can help, by offering consulting in Mathematica.
