For years, there has been a significant gear gap in underwater photography. On one side, you have simple action cameras — great for convenience, but limited in color depth and manual control. On the other, you have multi-thousand-dollar DSLR rigs that require a dedicated suitcase and years of experience to operate. Most divers fall somewhere in between, wishing for professional-grade results without the bulk and cost.
Enter UWACAM. Designed specifically for use with the DIVEVOLK SeaTouch housing — the only underwater housing that allows for full touchscreen control beneath the surface — this app does not just take photos. It re-engineers how your smartphone interacts with the ocean. Because the SeaTouch housing preserves native touchscreen functionality, UWACAM can offer an interface and feature set that no other underwater camera app can match.
This is the first article in our Recommended Apps for DIVEVOLK Users series, where we explore the best software tools that pair with your SeaTouch 4 Max to unlock its full potential underwater. If you want to move beyond blue-tinted memories and start creating professional-grade imagery, here is a deep dive into what makes UWACAM a must-have.

The Physics of Color: UWACOLOR Processing
The most frustrating part of underwater photography is the blue wash. As you descend, water absorbs different wavelengths of light — red disappears first, followed by orange and yellow. By 10 meters, everything looks monochromatic and cold. Standard camera apps have no way to deal with this, and a basic red filter is too blunt: too red in shallow water, not red enough in deep water.
UWACOLOR is UWACAM's proprietary solution. Unlike a static red filter, UWACOLOR is dynamically adaptive. It analyzes each scene in real time to restore the lost color spectrum, adjusting its correction intensity based on actual underwater conditions.
- Real-Time or Post-Processing: You can burn the color correction directly into your video as you film (up to 30fps), or capture clean footage and apply UWACOLOR in the app's playback gallery later.
- Three Levels of Intensity: Long-press the UWACOLOR button to toggle between three processing levels, so you can avoid over-saturating a shallow reef shot or under-correcting a deep wreck dive.
- Works with RAW: On supported devices, UWACOLOR can enhance RAW captures while preserving maximum detail and latitude.
Tailored to Your Skill Level: AUTO vs. PRO Mode
UWACAM understands that some dives are for relaxing, while others are for getting the shot. That is why it offers two distinct shooting modes.
AUTO Mode
Designed for the point-and-shoot experience, AUTO Mode simplifies the interface with large, thumb-friendly buttons. You get quick access to camera switching (Ultra-wide, Wide, and Telephoto) and basic video/photo toggles. It is ideal for snorkelers or divers who want to capture the moment without fumbling with settings.
PRO Mode
This is where UWACAM truly sets itself apart. PRO Mode unlocks a full suite of manual controls that rival dedicated cinema cameras:
- Manual Exposure and ISO: Prevent bright surface light or dark crevices from tricking your camera's auto-exposure.
- Grey Card White Balance: White balance is notoriously difficult underwater. In PRO Mode, use the Grey Card button to calibrate white balance against a physical slate or neutral object, ensuring accurate colors at any depth.
- Focus Peaking: On a small screen inside a housing, it can be hard to tell if a tiny shrimp or nudibranch is in focus. Focus Peaking highlights sharp edges in red, giving you instant confirmation.
- Zebra Stripes: Visual warnings that tell you when your highlights are blown out or overexposed — critical when shooting in bright shallow water.
- Histogram Display: A live RGB histogram overlay so you can monitor exposure distribution in real time.
Innovation in Orientation: The Upside Down Mode
One of the most creative features in UWACAM is the Upside Down Orientation. It solves a problem that every macro photographer knows well.
Most smartphones have their camera lenses at the top of the device. When shooting macro subjects — a nudibranch on the sand, a goby perched on a coral head — the body of the phone prevents you from getting the lens low enough for an eye-level shot. By enabling Upside Down mode, the entire UI flips, allowing you to hold the housing with the cameras at the very bottom. This puts your lens millimeters from the seafloor, creating that professional, low-angle perspective that makes subjects pop against their background.
This feature alone has changed how many macro lens users approach their subjects.
Cinematic Ambitions: Log, LUTs, and High Bitrates
For underwater filmmakers who want cinema-quality footage, UWACAM provides features usually reserved for dedicated video cameras:
- Apple Log Support: Capture video in a flat color profile that preserves detail in highlights and shadows. This gives you total freedom during color grading in Final Cut Pro, DaVinci Resolve, or your editing software of choice.
- Built-in and Custom LUTs: If you do not want to wait for post-production, import custom Look-Up Tables to preview your final color grade while you are still underwater. UWACAM ships with nine built-in LUTs optimized for different underwater scenarios.
- SMPTE Timecode: For professional workflows that require frame-accurate synchronization across multiple cameras.
- Camera Blending Control: When using external wet lenses like the DIVEVOLK Wide Angle Lens, toggle Camera Blending on or off to ensure the app uses the specific lens that provides the best optical result without digital artifacts.
AI Integration: Meet the Vizalyzer
Have you ever spent an entire dive staring at a strange creature, only to forget what it looked like by the time you reached your fish ID book on the boat?
UWACAM integrates with Vizalyzer AI. From the playback view, you can send any capture to the AI for analysis. It identifies marine species by scientific and common name, provides habitat information, and adds behavioral context — turning your photo gallery into a digital logbook of biodiversity.
While this feature requires an internet connection (so it typically happens back on the boat), it is invaluable for dive guides, marine biology students, and anyone building a personal species log. The AI is powered by a dedicated marine life database, so identifications are more reliable than general-purpose image recognition tools.
Navigation and Metadata
UWACAM is built to be a part of your complete dive kit, not just a camera:
- Compass Overlay: Keep a digital compass on screen while you film. This is a practical safety and navigation feature, allowing you to maintain your heading without looking away from your viewfinder.
- Location Tagging: Since GPS signals do not penetrate water, UWACAM uses your last known surface location to tag your photos. You can also manually enter coordinates or use satellite data to record exactly where you found that secret pinnacle or cleaning station.
Ethics and Safety: The UWACAM Philosophy
The UWACAM reference manual is not just about buttons and sliders. It includes a dedicated section on ethical underwater photography, reflecting values shared by the diving community and organizations like Project AWARE:
- Neutral Buoyancy: Never sacrifice the reef for a shot. Good buoyancy control is a prerequisite for good underwater photography.
- Marine Life Respect: Avoid chasing, cornering, or touching creatures. Patient observation yields better images than aggressive pursuit.
- Safety First: No photo is worth your life. The app reminds users to monitor air supply, depth, and buddy position — even when a once-in-a-lifetime moment is unfolding.
Post-Dive Workflow
Once you are back on the boat, UWACAM makes the editing process straightforward:
- Batch Processing: Select dozens of clips and apply UWACOLOR correction to all of them simultaneously. No need to process one file at a time.
- Flexible Storage: Save files directly to the iOS Photos app, a dedicated UWACAM album, or the Files app for better project organization.
- Smart Sharing: Built-in tools include an Auto-Crop feature that helps you format shots for social media platforms without losing the core subject.
Getting Started with UWACAM
UWACAM is available on both iOS and Android. The app is designed to work with the DIVEVOLK SeaTouch series of underwater housings, which are the only housings on the market that preserve full touchscreen functionality underwater. This means every slider, button, and gesture in UWACAM works exactly as intended — no mechanical buttons or awkward workarounds required.
If you are a DIVEVOLK user who has not tried UWACAM yet, it is the single most impactful upgrade you can make to your underwater photography without buying any new hardware. And if you are shooting on Android, the app just launched on your platform — read our full coverage of the Android release.
Quick tip: Before your next dive, practice on land. Familiarize yourself with the PRO Mode controls so that when a manta ray glides past, your focus is on the animal, not the screen.
