Siggraph 2018 - La Noria: Distributed Compositing with Nuke

HDR2Light is an image processing tool for decomposing lights from HDR images which essentially turns an HDR image (used as a skydome light) into its different contributing lights allowing them to be tweaked independently. The lights are extracted based on their distributed energy to preserve lights importance and the tool can be hooked up to different DCC applications and renderers.
