Underwater photography transforms portraits and fashion into something otherworldly — weightless fabric, floating hair, surreal light patterns, and an ethereal quality that no studio or outdoor setting can replicate. Whether in a swimming pool, the sea, or a cenote, shooting beneath the surface opens a completely different creative dimension. This guide covers equipment, techniques, lighting, safety, and applications for wedding "trash the dress" sessions, maternity, and creative portraiture.
Equipment for Underwater Photography
Underwater Housings
A waterproof housing encases your camera and lens in a sealed shell rated to specific depths. Housings are available from brands like Ikelite, Nauticam, Aquatica, and Sea & Sea. They range from polycarbonate (affordable, lighter, rated to 60m) to machined aluminium (professional-grade, heavier, rated to 100m+). Each housing is designed for a specific camera body and uses interchangeable port systems for different lenses.
Dome Ports vs Flat Ports
A flat port is a simple glass or acrylic window — suitable for macro lenses. A dome port is a curved glass hemisphere that corrects the refraction caused by water, restoring the lens's natural field of view. Wide-angle and standard lenses require dome ports; flat ports on wide lenses cause severe distortion and softness.
Underwater Lighting
Water absorbs light rapidly — reds disappear within the first few metres, leaving a blue-green colour cast. Artificial lighting restores natural colour:
- Underwater strobes: flash units in waterproof housings, attached to the main housing via arms. Provide powerful, colour-accurate illumination. Two strobes positioned wide of the housing minimise backscatter (light bouncing off particles in the water).
- Continuous LED lights: video lights that provide constant illumination — easier to preview the lighting effect but less powerful than strobes.
- Natural light: in clear, shallow water (swimming pools, cenotes), sunlight alone can produce beautiful results — rays of light streaming through the surface create dramatic patterns.
Camera Settings Underwater
- White balance: set to "underwater" mode if available, or use a custom white balance. In RAW, correct in post — the extreme colour cast is easily corrected if you shoot RAW.
- Aperture: f/5.6 to f/8 for portraits (some subject separation with acceptable sharpness). f/8-f/11 for scenics and wide shots.
- Shutter speed: 1/125s minimum to freeze motion — subjects and water move constantly.
- ISO: 200-800 depending on depth and available light. Higher ISO is needed deeper where light drops dramatically.
- Focus: autofocus works underwater but can be slower and less reliable through the port. Use continuous AF with face/eye detection if your camera supports it.
Shooting in Swimming Pools
The most controlled environment for underwater portraits. Advantages: clear, chlorinated water provides excellent visibility; controlled depth (subject can touch the bottom); warm water temperature; no currents or waves; controllable lighting. Most underwater portrait photographers work primarily in pools for these reasons.
For the clearest water and fewest air bubbles, shoot before the pool is used that day. Have the subject enter slowly and exhale gently through the nose to minimise bubbles. Bubbles can be artistic but can also obscure faces and fabrics.
Open Water Photography
Sea, lakes, rivers, and cenotes offer dramatic natural backdrops but present challenges: reduced visibility, currents, cold water, marine life, and unpredictable conditions. Open water shoots require more planning, safety awareness, and experience. The rewards are striking — natural rock formations, sunlight beams through ocean surface, and the vast blue expanse create images of extraordinary drama.
Underwater Wedding and Portrait Sessions
Trash the Dress Underwater
A wedding dress underwater is visually spectacular — the fabric billows, catches light, and creates flowing shapes impossible on land. The bride (or couple) submerges fully or partially while the photographer captures the scene from below the surface. Important: the dress becomes extremely heavy when wet, which restricts movement and can be a safety concern in deeper water. Brief the couple thoroughly.
Maternity Underwater
Flowing gowns and the weightless environment make underwater maternity sessions particularly beautiful. The water supports the body comfortably, the fabric frames the bump, and the ethereal quality of underwater light flatters skin tones.
Fashion and Fine Art
Underwater photography is widely used in editorial fashion and fine art for its surreal, dreamlike quality. Flowing fabrics, dramatic poses, and the suspended-in-space aesthetic create images that stop viewers in their tracks.
Safety
- Never shoot alone — always have a safety assistant or lifeguard present.
- Brief subjects on breathing techniques and safety signals before entering the water.
- Keep depths manageable — most portrait sessions work in 1-3 metres of water.
- Watch for fatigue — wet heavy dresses and repeated submersions are physically demanding.
- Check water temperature — hypothermia risk increases in extended sessions.
- For open water, understand currents, tides, and local hazards.
- Ensure subjects can swim confidently.
Post-Processing Underwater Images
- Colour correction: remove the blue-green cast in white balance. Restore reds and warm tones.
- Contrast: water reduces contrast — increase it in post to restore punch.
- Clarity and dehaze: slight haze from suspended particles can be reduced with dehaze and clarity adjustments.
- Backscatter removal: bright specks from particles lit by strobes — remove with spot healing or clone tools.
Underwater photography creates images that exist in no other medium — weightless, ethereal, and utterly unforgettable.
