Topic and Description
Presentation Topic: Cutting edge measurement tools for HDR workflows
Description: HDR/WCG technologies have added increased complexity in production workflows, starting with camera setup all the way to post production. For post production, HDR workflows create unique challenges: how do I transfer HDR artistic intent? How can I ensure that my HDR content fits within the end user's HDR display capabilities? We will consider a new set of HDR measurements that relate to the picture screen area, that aim to help answer these questions. For camera setup, each camera manufacturer has come up with their own way to compress and represent HDR content, leading to difficulties in both camera setup and in visualizing changes in light level (due to the non-linearity in the camera gammas). The talk will introduce a new type of waveform trace called as the "stop" waveform that aims to address these challenges.
