Sigmedia had a surprise visitor last week, Charles Ponyton,
The Sigmedia Team welcomed Charles to Trinity College Dublin and Trinity College Dublin School of Engineering on on a rainy Thursday. He had just given a Educational Masterclass at the National Talent Academies (Fís Éireann/Screen Ireland) about Colour Science and was keen to see what we were up to. He had just given a talk at the VFX Talent academy about Colour Science and was keen to see what we were up to. We gave him a tour of our work around Colour and HDR, Virtual Production, Denoising, AV2, learned-image compressions and the future of video/image coding…you know, the classics.
Over pints in O’Neils of Pearse Street, Charles regaled us with his war stories from his hard won technical breakthroughs over the years including some recent insight into film-grain. Onwards to better film grain management!
We also had the privilege to have our copy of his book signed. He said the front cover of our copy might be the most weather-beaten he has seen!
