We regularly receive questions from action cam users. How can I get more vibrant colors in my footage? What should I consider when it comes to lighting? Why are my shots so shaky, and how can I fix that? In this article, we share useful tips to help you level up your underwater action cam results.
Stability
New models like the DJI Osmo Action or GoPro Hero 13 now feature impressive image stabilization. This helps you capture smooth video, even if your hands are a bit shaky in cold water or during drift dives. Older models don’t always offer this feature—or not as advanced. But don’t worry: even with older cams, you can still shoot stable footage.
Tip 1: Film in slow motion
Set your camera to record in higher frame rates, such as 60 fps or 120 fps. Standard playback is around 24 or 25 fps. Slowing down footage recorded at higher fps gives it a cinematic look and helps minimize shakes. It’s also handy in post-production: extend short scenes, like a brief appearance of a manta ray, by slowing them down.
Tip 2: Use a tray with dual handles for your waterproof GoPro housing
Handholding or using a selfie stick often causes extra vibrations. A tray with two handles gives you more control and smoother movements. It’s a solid investment—plus, accessories like trays and lights are usually compatible with new cam models too.
Lighting: The Wider, The Better
The key is the beam angle of your video light. Many divers mistakenly use a regular dive light, which typically has a narrow beam (10–15 degrees). That’s great for visibility while diving, but not ideal for filming—action cams often have a wide field of view (140–170 degrees).
A narrow beam only lights a small part of your subject. Even worse, pointing that narrow beam straight at your subject lights up all the floating particles between your cam and your subject. Instead, choose a video light with a beam angle of 100–120 degrees. Aim it slightly away from the subject to avoid lighting up particles in the water column.
One or two lights?
If you use just one light, you’ll likely get harsh shadows. A second light helps reduce shadow zones and ensures more even lighting—especially helpful with wide-angle action cams.
How many lumens do I need?
That depends on where you're diving. In bright tropical waters, you'll need more powerful lights to compete with ambient light. In darker waters like in the Netherlands, a less powerful light will often be enough. Regardless of light power, try to stay within 1 to 1.5 meters of your subject to maintain color and clarity.
We also wrote a separate blog about underwater lighting for GoPro. You’ll find complete light packages with trays and arms on our website—so you won’t miss a thing!
Filters
Another way to improve color is by using a color correction filter.
Filter or video light?
That depends on the dive. Lights provide continuous illumination, but can scare away marine life. Be patient—don’t chase the fish, let them get used to you. Filters work well for wide-angle scenes like wrecks or reefs, where video lights can’t reach. However, filters require ambient light and are most effective in clear, tropical waters—not during night dives.
Flip filters and magnetic mounts
Using a T-Housing with your GoPro or DJI Osmo Action? You can mount a filter in front of the lens and safely flip it away using a magnetic holder when switching to lights mid-dive.
If you're using a GoPro Protective Housing, the GoPro flip system lets you easily switch between filters and macro lenses during the dive.
