I have used ACES color management for all of the HDR work I have done. Last week we gave a seminar on HDR to around 60 cinematographers. Based on that seminar, I have written this introduction to HDR.
You can read the article here: (http://www.finalcolor.com/hdr/)
There will be a second article in the series entitled: "ACES in Post Production."
This first article finishes with some reasons for using ACES to create good HDR, but I am interested to hear from others, particularly colorists, on how ACES has helped.
