Underwater color correction, answered.
Everything divers, freedivers and underwater filmmakers ask before they trust an app with their footage — the physics, the workflow, and how DeepColors handles it.
Common questions
What's the best app to fix the color of underwater video?
DeepColors corrects underwater photos and video automatically — the moment you open them — by recovering the red light that water absorbs with depth, then stretching each color channel for natural contrast. Unlike most dive color apps it grades video with keyframes, preserves HDR, and can export a .cube LUT or 4K HDR / ProRes for your desktop editor. It runs on iPhone, iPad and Mac.
Why does my scuba or GoPro footage look blue-green?
Water absorbs light by wavelength. Red is essentially gone by about 5 metres, orange by 10, and yellow by 20 — so with depth everything drifts toward blue-green. DeepColors reverses that absorption instead of just adding a fixed red filter, which is why the result looks natural rather than over-corrected.
Do I need a red filter on my camera if I use DeepColors?
No. A physical red filter helps but is fixed to one depth and steals light. DeepColors corrects in software after the dive, adapts to each shot, and with keyframes can follow a clip that changes depth. Many divers shoot without a filter and correct in the app instead.
Can I use DeepColors with DaVinci Resolve, Premiere or Final Cut?
Yes. Export your correction as a .cube 3D LUT and apply it in any editor that supports LUTs, so your DeepColors grade travels with the footage. Exact reproduction can vary with each editor's color management — DaVinci Resolve gives the closest match.
Does it work for freediving, snorkeling and pool footage too?
Yes. The correction is based on color analysis, not scuba-specific metadata, so it works for freediving, snorkeling, holiday reef clips and even swimming-pool footage.
Is DeepColors free?
It's free to download and try. A Premium subscription removes the watermark and unlocks .cube LUT export and 4K HDR / ProRes video export. There's no account, and your photos and videos are processed on your device rather than uploaded to a server (the subscription itself runs through Apple's App Store, like any iOS app).
Does DeepColors run on Mac?
Yes — it's a native Mac app as well as iPhone and iPad, sharing the same color engine. On Mac you can also open camera RAW files such as Sony .arw.
