Sony A7III SLog2

I am probably too late for the discussion. Anyways, I think both Slog2 and HLG can give excellent result. Both have very good dynamic range and decent color (this depends on personal preferences, of course). 

I used to struggle with color correcting SLog2 footage, but then I found the Color Space Transform tool in Resolve. Normally, I will simply transform the gamma and color space to Rec. 709 and start to do minor adjustments. It is much easier this way, IMO. I don't even need a LUT. 

Here are some of my old footage using the A7S2. I had forgotten to bring the ND filter so these were way way overexposed. Still, with a few clicks of buttons, I've got usable results. My girlfriend was happy with it, at least.

Would anyone be interested in LUTs that could be applied on S-Log2/S-Gamut3.cine clips on an ACEScct timeline? I extracted color information from Fujifilm profiles, and built special LUTs for ACEScct. The effect is subtle because the gamma is unchanged, only color is changed:

Normal S-Log2/S-Gamut3.cine clip on an ACEScct timeline, with only exposure adjustment:

Provia LUT applied:

Classic Chrome LUT applied:

I have all the other profiles as well.

Would anyone be willing share some SLOG or HLG footage for me to mess around with grading? I want to see if I like the looks I can get. 

I will try to get you some later. 

The footage I have was mostly shot with an ND filter and that might affect the colors a bit. So will probably want to shoot some new footage for you.

Thank you so much! That would be incredible.
