thebrothersthre3 Posted December 27, 2018 Share Posted December 27, 2018 Fooling around with HLG. Adjusted curves using a waveform and added some saturation. It definitely seems a bit cleaner then log. Skin tones looked good according to the vectorscopes.

webrunner5 Posted December 27, 2018 Share Posted December 27, 2018 Wow that looks nice. Just about a perfect exposure. Mark Romero 2 and thebrothersthre3 2 Link to comment Share on other sites More sharing options...
DanielVranic Posted December 27, 2018 Share Posted December 27, 2018 Okay, I am 100% new to HLG and everything. I took a test shot this morning, and I saw that there is a lot of latitudes, but getting the most of it required really stretching it in Resolve. What is everyone's HLG X-T3 workflow? I just perfected my FLog workflow like a week ago and now this LOL Link to comment Share on other sites More sharing options...

Expand Where did you get this information from? I'd be really interested in the specs for HLG to get a better understanding of the characteristics and how to grade it properly. Any white papers?

DanielVranic Posted December 28, 2018 Share Posted December 28, 2018 I have done about a dozen separate HLG vs FLog tests here and HLG has not looked better in any of them. Low light capture is significantly better with Flog, maybe a full stop more captured information. Flog has been cleaner and easier to work with by a huge factor. I will still aim that way unless an awesome HLG workflow comes out. Link to comment Share on other sites More sharing options...

Expand HLG can be either 10bit or 12bit per BT.2100 standard. X-T3 is BT.2100 compliant and can only record using HEVC codec when HLG mode is selected. Since HLG is an open standard, Sony decided to deviate from the standard and used 8bit encoding, along with various HLG curves. Link to comment Share on other sites More sharing options...

Also, I haven't posted samples yet because upon further testing my processing chain was wrong.

MeanRevert Posted February 28, 2019 Share Posted February 28, 2019 Hey guys, Just following this interesting thread waiting for my camera to arrive.. You guys still going down the Flog route or is HLG the way to go? I've seen some good side by side from camtheman and the hlg looked great. Any new info since this thread?

Expand I used the offical Fuji FLog luts, and created some using LutCalc. For HLG I used the Color Space Transform node in Resolve, and tried out the HLG LUTs that came packaged with Resolve. Overall i found it much easier to get the result i wanted when using HLG. Link to comment Share on other sites More sharing options...
