I bought these LUTs and applied them to the Sigma fp's CDNG files. IMO they look great.
Lens: Nikon 28mm f/2.8 non-AI.
Here's my workflow:
1. Set colorspace and gamma to BMD/BMD Film
2. Make any RAW adjustments needed (WB, exposure, shadow/highlights, etc)
3. Add a node and apply the BMD Pocket 6K Extended Video LUT (to flatten highlights even more)
4. Add a second node and use a Rec709 LUT to add a look
5. Grab the still, then in the Gallery apply the look to the rest of the clips, making adjustments as need.

And now, for the stills. Straight out of camera:

In Resolve's Camera RAW, set Color Space and Gamma to Blackmagic Design / Blackmagic Design Film.

So I converted film/log gamma into Rec709. This will be the base grade. I chose Extended Video instead of Video because it preserves highlights better. To do this, in first node, I set the LUT to Blackmagic Pocket 6K Film to Extended Video v4.

The rest of these stills show the OSIRIS LUTs applied to the second node, after the base grade. I toyed with setting the output opacity to 50-75%, but I left it at 100% for this demo. If I were working on a real project, I would dial down the look a bit. And now the LUTs...
