This is actually one of the things I tried in my own tone chasing, and it’s good advice! I left a comment about the settings I used with that equipment that worked well for me.
The answer was then deleted and converted to a comment, which I don’t understand. The answer is an answer to my question, and a helpful answer too, just a bit too brief, so why was it deleted instead of improving it? Especially since there was a comment on the answer that showed exactly how it could be improved.
