Every diver's footage comes back blue-green — the question is how far you want to take fixing it. This is a plain, capability-first look at what separates a quick filter from a real grading tool, and where each kind of option makes sense.
Does it recover the red light water absorbs on its own, or leave you pushing sliders by hand? The best tools nail a natural base look the moment you open a file and let you refine from there.
Some apps only touch stills. If you shoot clips as well as photos, one consistent engine for both saves you re-learning a second tool.
A dive clip changes depth as it plays. Only apps that keyframe the grade across a clip can keep it corrected from the shallows to the deep.
Sun shafts and surface glare blow out to flat white without an HDR-aware pipeline. This is where cheap filters and quick fixes fall apart.
If you finish in DaVinci Resolve, Premiere or Final Cut, being able to export a .cube LUT means your correction travels with the footage.
Camera RAW support and high-bit-depth, 4K or ProRes export separate a serious grading tool from a social-sharing filter.
iPhone-only, or Mac too? On-device, or does your footage get uploaded to a server? For many divers, keeping files local matters.
Purpose-built correction tools that handle photo and video, offer manual control on top of an automatic fix, and export for a real edit. DeepColors sits here — and pushes furthest on HDR, keyframing, LUT export and Mac support.
Apps that bundle a quick color filter into a social feed or dive-logging tool. Convenient if you already live in that ecosystem, but the correction is usually a single fixed filter with little control and no pro export.
Lightweight apps that apply one automatic underwater filter. Great for a fast share, but they typically skip HDR, video keyframing, LUT export and RAW.
The most powerful option — and the steepest learning curve. Ideal for finishing, especially when you feed them a .cube LUT built on your phone right after the dive.
Measured against the capabilities typical dive color apps offer.
| Capability | DeepColors | Typical dive color apps |
|---|---|---|
| Automatic underwater correction on import | ||
| Photo and video in one app | Some | |
| Keyframe video grading | ||
| HDR-preserving pipeline | ||
| Export .cube LUTs for Resolve / Premiere | ||
| 4K HDR & ProRes 422 / 4444 export | ||
| Manual channel mixer & tone curve | Some | |
| Camera RAW support (macOS) | ||
| Native Mac app, not just iPhone | ||
| No account; your footage never leaves your device | Some |
If you only need to share one clip, almost anything works. If you want your dives to look the way they felt — and to keep grading them as you get more serious — these are the things we wouldn't give up:
