LuttieLUTs for Sony S-Log3
S-Log3 records far more range than a display can show, which is why footage comes off the card grey and flat. These convert it to Rec.709 and apply a look in the same file.

Convert S-Log3 before you grade it
Log footage is recorded flat on purpose: it holds highlight and shadow detail far outside what a display can show. A look LUT does not expand that range, so applied straight to log the image stays washed out and the highlights stay dead. Convert to Rec.709 first, then grade on top. Technical transform, then look, in that order.
The workflow
Shoot S-Log3 with S-Gamut3.Cine
The gamut matters as much as the curve. S-Gamut3.Cine is the one these LUTs are built against.
Expose to the right
S-Log3 is noisy in the shadows. Rate it 1 to 2 stops over and bring it back in the grade.
Convert to Rec.709
Apply a conversion once, at the bottom of the stack. The Luttie pack does this and the look together, so you do not stack two conversions.
Grade on top
Contrast, white balance and secondaries go above the conversion, never below it.

Questions
Yes. Any Sony body shooting S-Log3 with S-Gamut3.Cine is covered, including the A7S III, A7 IV, FX3, FX30, FX6, FX9, A1 and VENICE.
No. Each LUT in the pack contains the S-Log3 to Rec.709 conversion already. Stacking Sony's conversion underneath one of these applies the transform twice, which is the most common way this goes wrong.
Yes. Open the footage in the Luttie editor, which runs in the browser with no install, and grade it with curves and colour wheels. The pack is a shortcut, not a requirement.
They are built for S-Log3. S-Log2 has a different curve, so the conversion will be off. Grade S-Log2 manually in the editor instead.
