How to export V-log TIFFs from Panasonic RW2 files?

[Entropy512 (Andy Dodd)]

There was a discussion on this very subject a year or two ago. That resulted in me generating an ICC profile set which used the V-log TRC…

Ah, found the old thread:

Converting S1H raw files to V-Log gamma

The Panasonic S1H has what looks like a brilliant feature for photographers… the ability to monitor through a 3D LUT. However, when I take a photo with the V-Log profile, the raw file (.RW2) that comes out looks nothing like a log file (using the jpg as a reference, which is encoded with the V-Log profile), through any software (capture one, raw therapee, exposure, Davinci Resolve [converted to DNG]). I also have a Varicam LT and when I shoot raw cDNG files externally to an Atomos Shogun Inferno…

I may rewrite that profile generator tool in Python at some point soon, but I THINK there are relevant ICC profiles attached in the other thread. You can use these profiles as output profiles in RawTherapee with the “Neutral” processing preset and that should put you pretty close to the OOC V-Log JPEGs. Otherwise I’ll try to rerun the generator and attach a V-Log+V-Gamut ICC here in a day or two.
