2How underwater photography works
The fundamental principles of photography apply underwater, but with significant modifications. Water absorbs light, especially warmer colours like red and orange, meaning that colours appear muted or absent at depth. To counteract this, underwater photographers often use external artificial light sources, such as strobes (flashes) or continuous video lights, to restore natural colours and illuminate subjects.
Refraction, the bending of light as it passes from water to air (or vice versa), causes subjects to appear larger and closer than they actually are. This effect is managed by using dome ports for wide-angle lenses or flat ports for macro lenses, designed to correct for these optical distortions. Good buoyancy control is paramount, not only for safety and preventing damage to the environment but also for stable framing and precise focus.
Post-processing is also a critical step in underwater photography. Software like Adobe Lightroom or Photoshop allows photographers to correct colour casts, enhance contrast, sharpen images, and remove backscatter (small particles illuminated by artificial light), transforming raw images into vibrant, high-quality photographs.

| Feature | Compact/Action Camera | Mirrorless/DSLR (Amateur) | Mirrorless/DSLR (Professional) |
|---|---|---|---|
| Typical Cost | £500-£1,500 (€580-€1,740 / $620-$1,860) | £2,000-£5,000 (€2,320-€5,800 / $2,480-$6,200) | £8,000+ (€9,280+ / $9,920+) |
| Ease of Use | High | Medium | Low (complex controls) |
| Image Quality | Good | Very Good | Excellent |
| Customisation | Limited | Moderate | Extensive |
| Buoyancy | Neutral to slightly negative | Slightly negative | Can be significantly negative |
4What underwater photography means for your liveaboard trip
Liveaboard trips are ideal for underwater photographers due to the multiple daily dives, access to remote and diverse dive sites, and the extended time spent in prime photographic locations. Many liveaboards are equipped with facilities specifically designed for photographers, including dedicated camera rinse tanks with fresh water, spacious camera tables for assembly and disassembly, and ample charging stations.
The schedule of a liveaboard often allows for dedicated photography dives, sometimes even offering night dives or blackwater dives that present unique photographic challenges and opportunities. Divers can spend hours refining their skills, experimenting with different subjects, and capturing a wide array of marine life without the logistical constraints of shore-based operations.
For those travelling with professional camera gear, it is important to communicate equipment needs to the liveaboard operator in advance. Some liveaboards may offer services like photo workshops or on-board photo experts, which can be invaluable for improving techniques and learning new skills during the trip.
5Key regions for underwater photography
| Region | Best for Macro | Best for Wide-angle | Notable Subjects |
|---|---|---|---|
| Coral Triangle (Indonesia, Philippines) | Excellent | Excellent | Nudibranchs, pygmy seahorses, reef sharks, manta rays |
| Red Sea (Egypt, Sudan) | Good | Excellent | Soft corals, historic wrecks, barracudas, reef fish |
| Galapagos Islands (Ecuador) | Limited | Excellent | Hammerhead sharks, marine iguanas, mola mola, sea lions |
| Maldives | Moderate | Excellent | Manta rays, whale sharks, reef sharks, healthy coral reefs |
| Caribbean (Bonaire, Belize) | Good | Good | Macro critters, healthy reefs, sponges, smaller wrecks |
6Common misconceptions
Myth: Underwater photography is only for professional divers. Fact: While advanced skills help, modern compact cameras and action cameras with underwater housings make it accessible for recreational divers. Many dive centres and liveaboards offer workshops to help beginners.
Myth: You need very expensive gear to take good photos. Fact: While high-end equipment offers more control and quality, excellent photos can be captured with mid-range or even entry-level setups. Mastering lighting, composition, and buoyancy often matters more than camera specifications.
Myth: Flash is always bad underwater. Fact: External strobes (flashes) are crucial for restoring lost colours and illuminating subjects, especially at depth. The key is proper positioning to minimise backscatter and create natural-looking light.
Myth: You can just point and shoot underwater like on land. Fact: The underwater environment drastically changes light, colour, and perspective. Understanding how water affects optics and light, along with mastering buoyancy, is essential for successful 'point and shoot' results.
FAQ
What is the biggest challenge in underwater photography?
The biggest challenge is dealing with the properties of water, which absorbs light (especially red and orange colours) and causes subjects to appear closer and larger due to refraction. This necessitates specialised equipment and techniques to correct for colour loss and optical distortion.
Do I need a special camera for underwater photography?
You don't need a specific camera brand, but you do need a camera with an appropriate underwater housing. Housings are pressure-rated cases that protect your camera and allow control over its functions underwater. Some cameras are waterproof without a separate housing but are typically limited to shallow depths.
What is backscatter and how can I avoid it?
Backscatter refers to small particles (like plankton or sediment) in the water column that are illuminated by your strobe or light, appearing as bright dots in your photos. It can be avoided by positioning your external strobes or lights away from the camera's lens axis, typically on extended arms, to illuminate the subject directly rather than the water in front of the lens.
Why do my underwater photos look blue or green?
Water absorbs warmer colours (reds, oranges, yellows) as you go deeper. This leaves primarily blue and green light to reach your camera, resulting in a colour cast. Using external artificial lighting (strobes or video lights) is the most effective way to reintroduce these lost colours and achieve accurate white balance.
Can I learn underwater photography on a liveaboard?
Yes, many liveaboards are excellent environments for learning. Some offer dedicated photography workshops or have onboard photo pros who can provide guidance. The multiple daily dives also offer ample opportunity to practice new skills and techniques.
What's the difference between macro and wide-angle underwater photography?
Macro photography focuses on small subjects, capturing intricate details of tiny marine life using close-up lenses. Wide-angle photography aims to capture large scenes, such as reefs, shipwrecks, or large marine animals, often using dome ports to achieve a broad field of view.
