The EBU helps its Members use High Dynamic Range (HDR) to provide stunning images. This forms part of the work performed in the HDR Implementation Task Force, the HDR Downmapping group, and the Video Systems group.
HDR Workshop 2022
In May 2022 a hands-on Workshop dedicated to HDR workflows was held at EBU Member SWR.
This event was preceded by a number online HDR webinars in which we look at current HDR production workflows of NBC Universal, BT Sport, HBS, the BBC, and Sky UK. See the events list for more details.
