Re: [Avid-L2] Color Science etc... Log vs. ACES?

Last time I checked, DP will shot using Sony Log format (wider color space) either S-Gamut3/S-Log-3 or  S-Gamut2/S-Log-2 and monitor using ACES LUT to whatever their monitor is set to (Rec.709 or P3 usually). I don't think Sony cameras have a specific settings for ACES, other than accepting ACES LUT for monitoring your output signal. To answer your question, the camera settings are the same than shooting log, but in order to get the look the DP is looking for, they want to use some ACES LUT corresponding to the established look.

In post, to work in ACES, you want to use the Sony IDT when processing the corresponding footage.

For a "true ACES" workflow in DaVinci Resolve, you want to switch Color management to ACES (ACEScct, latest version 1.03) and use the Sony IDT for your footage in the Media page.

Hope this help,

I may have a project that will be shot on Sony F55s and I'm told production is using an ACES workflow.  I've played with ACES in class but it was very brief.  How does ACES differ from shooting Log in practice?  I haven't had a chance to contact any of the production folks to find out exactly what ACES mode they will be using.  Does the F55 shoot in typical SLog3 but store information in ACES or is it just set to record ACES of a certain type?

In Resolve I know there a are project settings that get Resolve to work in ACES color science as opposed to the typical Resolve color science.  I have no media to play with yet so just starting to experiment and learn what I can.
