You surfaced from a perfect dive. The reef was vibrant, the light was soft, and a turtle glided right past your lens. But when you open the gallery later, every shot looks flat, blue, and lifeless. Sound familiar? The truth is that capturing a great underwater image is only half the job. Water strips red and orange wavelengths out of every frame long before they reach your sensor, and no amount of in-camera magic fully replaces them. The other half of the work happens at the editing desk — and the most accessible, most powerful tool for that job is Adobe Lightroom.
Welcome to Master One Underwater App a Month, our series where we take a single piece of software that pairs with your DIVEVOLK kit and learn it properly — front to back, one month at a time. Last time we went deep on the camera-side workflow with UWACAM, the underwater camera app built for SeaTouch housings. This month we move downstream to the edit: how to take the RAW files you shoot through a DIVEVOLK underwater housing and turn them into images that look like the dive actually felt.
Why Lightroom for Underwater Photos?
Lightroom comes in two flavors that matter to divers. Lightroom (the cloud-based version) runs on desktop, iPad, and phone, syncing your edits across all of them — ideal if you shoot RAW on your phone inside a housing and want to edit on the same device between dives. Lightroom Classic is the desktop-only powerhouse for photographers who manage large libraries locally. Both share the same core editing engine, so the adjustments below translate directly between them.
The single most important habit to adopt: shoot RAW whenever you can. RAW files hold far more color and tonal information than JPEGs, which means you can recover the red channel that water destroyed without tearing the image apart. Modern smartphones shoot RAW (Apple ProRAW or Android DNG), so if you are capturing through a SeaTouch 4 Max kit, you already have the raw material a strong edit depends on. For a primer on getting those captures right in the first place, see our complete guide to underwater smartphone photography.
Step 1: Import and Cull Ruthlessly
A single dive can produce hundreds of frames, and most of them will be near-duplicates or misfires. Before you touch a slider, cull.
- Import everything into a dated album or collection named for the dive site, so your library doubles as a visual dive log.
- Flag and rate. Use the pick flag (or star ratings) to mark keepers on a first pass. Reject the obvious throwaways — blown-out surface shots, motion blur, empty blue water.
- Zoom to 100% to check focus. On a small housing screen it is easy to think a nudibranch is sharp when it is not. Confirm critical focus before you invest editing time.
Treating your gallery as a logbook pays off later. If you want to push that idea further, our piece on telling your dive story through photos covers how to organize and caption images so the memory stays attached to the frame.
Step 2: Fix the Color Cast (White Balance)
This is the edit that matters most. Underwater photos suffer from a heavy blue or green color cast because water absorbs warm wavelengths with depth. Your goal is to add that warmth back.
In the Color (Basic) panel, start with the White Balance eyedropper. Click it on a patch that should be neutral gray or white — a sandy bottom, a diver's gray fin, or a section of pale rock. Lightroom recalculates the entire image around that reference, often snapping the scene from murky blue to something close to natural in one click.
From there, fine-tune by hand. Drag the Temperature slider toward yellow to warm the image, and nudge the Tint slider toward magenta to counteract the green that often lingers, especially in temperate or plankton-rich water. There is no single correct value — depth, time of day, and water clarity all change the starting point, so trust your eye and the histogram over any fixed number.
Step 3: Exposure, Contrast, and Dehaze
With color roughly corrected, set the overall tonality.
- Exposure: Adjust for the main subject, not the background blue. Recover blown highlights by pulling the Highlights slider down, and open up dark crevices with Shadows.
- Contrast and the tone curve: Underwater images often look soft and low-contrast because of the water column between you and your subject. A gentle contrast boost or a subtle S-curve restores punch.
- Dehaze: The Dehaze slider (in the Effects panel) is tailor-made for underwater work. A small push — somewhere around +15 to +30 — cuts through suspended particulate and instantly adds clarity and contrast. Use it sparingly: too much crushes shadow detail and exaggerates any backscatter in the frame.
Step 4: HSL and Color Calibration for True-to-Life Reefs
Global white balance gets you most of the way, but the Color Mixer (HSL) panel is where reefs come back to life. Work channel by channel:
- Reds, oranges, and yellows: Gently raise Saturation and Luminance on these channels to revive the warm tones water stole — the rust of a sponge, the gold of a sea fan.
- Tame the cyan: A common pro move is to "ban the cyan" — shift the Aqua hue toward blue and pull its saturation down so the background water reads as a clean blue rather than a sickly teal.
- Greens on sand: If the seafloor looks green, reduce green saturation to neutralize it.
For deeper color accuracy, the Calibration panel (adjusting the primary Red, Green, and Blue channels at the sensor level) gives a more organic correction than HSL alone and is the secret behind many commercial underwater presets. Move these sliders subtly — small shifts here ripple across the whole image.
Step 5: Noise Reduction and Sharpening
Low light at depth pushes ISO up, and smartphone sensors in particular introduce noise. In the Detail panel, apply Noise Reduction — or use Lightroom's AI-powered Denoise feature on RAW files for a remarkably clean result — then add Sharpening to bring back fine detail on scales, eyes, and coral texture. The order matters: reduce noise first, then sharpen, so you are not sharpening the noise itself. Good lighting at capture time means less noise to fight later; a pair of underwater video lights restores warm color at the source and keeps your ISO down.
Step 6: Local Adjustments and Backscatter Cleanup
Global edits only go so far. Masking is where an image goes from good to gallery-ready.
- Subject masks: Lightroom's AI Select Subject can isolate a fish or diver so you can brighten or warm it independently of the background.
- Radial and linear gradients: Darken a distractingly bright corner of surface light, or add a subtle vignette to draw the eye to your subject.
- Backscatter removal: Those annoying white specks — suspended particles lit by your strobe or lights — are the bane of underwater shooters. Use the Healing and Remove tools to spot out individual particles against open water. Lightroom handles light to moderate backscatter well; for a frame absolutely littered with it, the more powerful tools in Photoshop are worth the round trip, a point echoed by specialists at the Underwater Photography Guide. The best fix, of course, is prevention: position your lights wide and slightly forward to keep particles out of the beam.
Step 7: Presets and Batch Sync
Once you have nailed the look on one image, you rarely want to start from scratch on the next forty.
- Save a preset. Capture your white balance, HSL, and dehaze settings as a custom preset named for the conditions ("Tropical Reef 10m," "Green Water," "Wreck/Deep"). Build a small library that matches the sites you dive.
- Copy and paste settings. For a batch of frames shot in the same conditions, copy the settings from your hero edit and paste them onto the rest, then fine-tune individually.
- Sync across the album. Lightroom's sync feature applies one edit to every selected image at once — a huge time-saver after a multi-dive day.
Presets are a starting point, not a finish line. Lighting and depth vary shot to shot, so always do a final per-image pass on white balance and exposure.
Step 8: Export for Where It's Going
Match your export to the destination:
- Web and social: Export as JPEG, sRGB color space, with the long edge sized for the platform (around 2048px is plenty for Instagram). Quality around 80% balances sharpness against file size.
- Print or archive: Export full-resolution TIFF or maximum-quality JPEG in a wider color space for the best fidelity.
- Keep the original. Lightroom edits are non-destructive, so your RAW file is always untouched — you can revisit and re-edit any image as your skills grow.
From the Surface to the Story
Editing is not about faking a dive that did not happen — it is about restoring the color and clarity that physics removed on the way to your sensor. Master these eight steps and your gallery will finally match your memory. The reward is sharper, truer images that do justice to the places you dive, whether you are building a portfolio or planning your next trip to one of the best dive destinations for underwater photography.
Great edits start with great captures, and great captures start with full touchscreen control of your phone underwater — exactly what the SeaTouch 4 Max Platinum housing delivers. Questions about pairing your gear with your editing workflow? Our team is one message away on the contact page.
