Hi all, the last GoPro I had was Hero4, until my brother lost it diving :-(. Before that I had a Hero2. I have always used a red filter for diving. I am going on a dive trip to La Paz next month and want to get a Hero7. With the newer cameras, what's the latest, should we still use filters, or do color grading in post, use at depth white balancing, what is recommended? Thank you very much
