Underwater filming is one of the most exciting ways to expand your creative work — whether you’re vlogging, capturing snorkeling scenes, or simply recording memories from your tropical adventures. Action cameras like the DJI Osmo Action 4 (I shot underwater using) have taken this art form to the next level, combining rugged build quality with advanced imaging capabilities.
In this CameraLab guide, we’ll walk you through how to set up your action camera for successful underwater shooting, including best settings, practical tips, and real-world insights based on hands-on testing.
Why Action Cameras Excel Underwater
Action cameras like the DJI Osmo Action 4 are ideal for underwater shooting because:
Built-In Waterproofing
The Action 4 is waterproof up to 18 meters (60 feet) without requiring a case — rare at this price point. For deeper dives, an additional housing gives you extended protection and peace of mind.
Advanced Stabilization
Today’s action cams feature powerful stabilization systems. With RockSteady+, the Action 4 delivers impressively smooth motion — especially helpful when swimming or moving through choppy water.
Dual Display for Framing
Front and rear screens make it easier to frame shots when underwater — essential for vloggers and content creators who shoot themselves or others.
Small, Versatile, and Unobtrusive
A compact camera is less intimidating to subjects, and more adaptable for creative angles — from ground level to submerged reef shots.
Action Cam Settings for Underwater Shooting
Here’s how CameraLab recommends setting up your action cam before entering the water:
1. Resolution & Frame Rate
- 4K at 60fps — Ideal balance of resolution, smooth motion, and performance
- 120fps available for ultra-slow motion, but 60fps provides consistent quality and battery efficiency
This is where Action cameras truly shine — high-resolution capture with smooth motion for vivid underwater scenes.
2. Field of View (FOV)
Underwater footage benefits from immersive perspectives:
- Wide or Ultra Wide — Perfect for capturing coral reefs, schools of fish, or swimming sequences
- Standard (D-Warp) — Reduces lens distortion for straighter horizons
At CameraLab, we prefer Wide mode for underwater storytelling — showing more context around the subject without unnatural distortion.
3. Stabilization Mode
Always enable strong stabilization:
- RockSteady or RockSteady+ – Best choice for underwater shots
- Avoid heavy digital cropping unless you need horizon leveling — it reduces your field of view
Stabilization is crucial underwater because your body and water motion can make handheld filming unpredictable.
4. Color Profiles
Choose based on your post-processing flow:
- Normal Color – Great straight out of camera
- D-Log M 10-bit – Best for professional editing and color grading
At CameraLab, we recommend the D-Log M profile if you plan to edit footage — it preserves more highlight and shadow detail, especially in blue-dominant underwater light.

Real-World Tips from CameraLab
📌 Preparation and Battery Life
One mistake many creators make: not charging before hitting the water. You can’t swap batteries underwater, so start fully charged. At 4K60, the Action 4 records up to 90 minutes per battery. Using a multi-battery charging case lets you rotate quickly between dives.
📌 Use a Floating Handle
Action cameras sink if dropped. We strongly recommend a floating grip to avoid losing your camera in surf, waves, or deeper water.
📌 Choose Ideal Conditions
For magical underwater footage, look for:
- Sunlight (light penetrating the water)
- Clear water
- Blue skies
This combination maximizes color and contrast, making your footage look cinematic.
📌 Focus on One Main Subject
Underwater environments are visually busy. Instead of capturing everything at once:
- Pick one subject — a fish, diver, or coral
- Film that clearly
- Move on to the next
This keeps your storytelling focused and prevents editing confusion.
📌 Maintain Proper Distance
Get too close and your lens may distort or struggle with focus. Keep a comfortable distance — action cams are made to capture wide scenes, not macro close-ups.
📌 Try Multiple Angles
Mix camera angles:
- Look down from the surface
- Look up from beneath
- Place the camera near rock formations
Different angles transform ordinary shots into cinematic sequences.
Practical Shooting Challenges
Even great action cams have limitations underwater:
🔹 Touchscreens may be less responsive with wet hands
🔹 On-screen preview may be limited while recording
🔹 Color balance changes with depth and lighting
CameraLab’s tip: set defaults before entering water and trust your settings rather than touching the screen mid-dive.
CameraLab’s Underwater Verdict
After extensive testing, we can confidently say the DJI Osmo Action 4 is one of the strongest action cameras for underwater use today. Its combination of stabilization, waterproofing, and image quality makes it a top choice for creators who want:
✔ Color-accurate footage straight out of camera
✔ Powerful stabilization for shaky conditions
✔ Dual screens for easy framing
✔ Compact gear that goes anywhere
No action camera is perfect underwater, but the Action 4 comes remarkably close.
