If I swam in that position, I would get sooo much water up my nose, I'd think I was waterboarded! Some great footage you have managed to capture there, well done. I'm surprised that you were able to post to YouTube with that copyrighted Movie...
Humpbacks of Australia. - Youtube.
I've been revisiting some clips i took last season. In regard to the drone clips - taken on both an Air2s and a Mavic 3 pro - i'm just really struggling with colour grading.
I use Imovie and am very comfortable...
