What’s Inside

  • Quick-settings cheat card — exact resolution, frame rate, aperture, ISO, white balance and filter for every scenario: snorkel, reef, deep, wreck, night, fast action, and split-level over-unders.
  • Bare vs. cased — the real depth limits (and why 20 m “waterproof” doesn’t mean dive it to 20 m), plus a straight DJI vs. Telesin vs. Sea Frogs case breakdown.
  • Macro & wide-angle underwater — which lenses genuinely work down there, including hands-on Inon wide + macro results on the Action 6.
  • White balance & filters — red vs. magenta, when to use each, and how to get clean color straight out of the water.
  • Low-light & SuperNight — settings for wrecks, caves, and night dives where the big sensor and f/2.0 earn their keep.
  • Editing — a DaVinci Resolve grading workflow for D-Log M dive footage, so your color doesn’t fall apart in post.

Who Made It

I’m the OldDiver. I’ve been diving for 56 years / 1000+ dives and shooting underwater the whole time, currently from Bonaire. I built this guide because I wanted it to exist and it didn’t — so I’m giving it away to the diving community. If it helps you get better footage, come say hi on YouTube or drop by my website OldDiver.com to see what’s up.

Found an error or have a correction? This is a living document and the Action 6 is brand new — email me at OldDiver.com@gmail.com and I’ll get it fixed. Better info helps every diver who downloads this.

Free means free. No email gate, no mailing-list trick, no affiliate fine print. Prices and a few brand-new accessories in the guide are flagged “verify before buying” because the Action 6 is recent — I’d rather tell you what I don’t know than pretend.
