Achieve a Log image for post workflow

Hey,

could someone please detail how to export and achieve a log image with the spark? I am using Davinci. I am exporting as cinemaDNG but it still has a backed on 709 look. 

thank you

change your RAW settings to Blackmagic Design Film - I’d personally run a CST on top on your first node but thats obviously dependent on what you’re doing with it.

Cheers!
