Fuji Flog To HDR Grading Step By Step
Channel: Homebrew HDR
Date: 2021-04-23

I walk though (literally) how I graded a challenging landscape (Hendryd waterfall) clip captured in FLog ito HDR.  HDR grading is nothing like grading for SRD (for me at least); the challenge is retaining the beauty and naturalness of the original, not trying to make it look good in a limited medium.

All done using free tools and my free luts. However, this should be generally applicable to any tool capable to handling HDR.

Settings used:
First section curves: 0/0 0.05/0.05 0.2/0.3 0.5/0.6 0.9/0.9 1/1
First section unsharp: 0.2(amount) 32 (radius)
Second section curves: 0/0 0.5/0.75 1/1
Second section brighten: 1 1 1.1 1 1 1
Second section unsharp: 1 (amount) 2 (radius)
