Thanks for this in-depth answer Orash, I really appreciate it and it gave me a wider understanding of using ACES.
Last question though, in our workflow, grading comes first then the vfx artists will match their comps with the grade, then if there are fixes to be made in the grading it will be post graded in the online with the output of the vfx artists, meaning I will not go back to the original grade, if it's only minor fix ups. In using ACES in the grading, the only advantage of using it is the color space right? If my output will be non ACES? Is our workflow ideal or should we revise it? Most of our projects are commercials. Thanks!
