With the release of the AtomOS version 11 for the Atomos Ninja V, I took a (fresh) look at OM-Log400 and how to grade it. I've never really been a great fan of Log400, I mainly us the Flat profile, but as it seemed that there might have been some changes in Log400 processing in the Ninja with the new OS, I took a deep dive into Log400 and how to grade it on Resolve. My main interest was to find if I should re-evaluate my choice fo "Flat" vs "Log400" as well as see if I could find a simple grading workflow that would help myself get results that I'm satisfied with.

Spoiler alert:
- Don't think I will go from "Flat" to "Log400"
- Yes, I did find a reasonably good but perhaps a bit unorthodox workflow for Log400.

The video concerns the E-M1 mark ii but I assume (but have not tested) that the observations also apply to the OM-1.
