Thanks Colin, Geoff and Nick,

Both of those methods seem to work a treat. 

Using the OFX tool Colour Space Transform in YRGB mode, lets me get back to SLOG3/Sgamut3.cine (or close enough at least).

And ACEScct + no IDT + rec709 ODT brings me to a neutral Rec709 space in ACES.

Cheers,

If you don't want to work in ACES mode, you can use the ResolveFX Color Space Transform to convert to e.g. S-Log3 / S-Gamut3.Cine, so you can, for example, use a LUT designed for that. 

You will need to convert both the gamma (linear to S-Log3) and gamut (ACES AP 0 to S-Gamut3.Cine). ACES also has a different white point, so you will need to apply a chromatic adaptation from ACES white (~D60) to D65. I am not in front of a Resolve system right now, so I don't know how (or if) the Color Space Transform effect handles white point adaptation.

I've pulled the EXRs into Davinci to have a play around with them. But I haven't worked with EXRs before, and I'm struggling to convert them from Linear, back to a conventional Sony SLOG3 gamma that I can then work from.
