On World Oceans Day, learn to take underwater photos more sustainably

Beneath the ocean’s surface is nature’s living art exhibition. Coral reefs are a testament to the beauty and diversity of life below water. As sunlight pierces the surface, it illuminates the coral colonies revealing an explosion of colours, each housing its own fascinating ecosystem.

In this underwater wonderland, the colours shimmer and change with the ebb and flow of the tides. The ever-changing symphony of vibrant hues and myriad species has attracted humans in a bid to capture the perfect moment through underwater photography.

However, it is estimated that 88 per cent of divers touch, trample or make other harmful contact with a reef at least once during a dive. Research shows that 74 per cent of divers carry a camera underwater, increasing the chances of contact with delicate reefs.

World Oceans Day, which is 8 June, is casting a spotlight on this problem.

“Taking beautiful photos and sharing them with the world is one of the ways we show our appreciation for the majesty of the ocean and the biodiversity it supports,” said Leticia Carvalho, Head of the United Nations Environment Programme’s Marine and Freshwater Programme. “On this World Oceans Day, let us celebrate the beauty of blue ecosystems sustainably,” she added.

Carvalho is an oceanographer and avid diver. Based on the best practices of UNEP's Green Fins Initiative, implemented in partnership with The Reef-World Foundation, she has five recommendations to current and potential underwater photographers on how to take photos more sustainably. 

Respect marine life

Whenever you get into the water, considerations for the welfare of ecosystems and their inhabitants should be top priority. The tourism sector, according to the UN Chronicle, has committed itself to preserving life below water, while recognizing that the long-term economic potential of tourism depends on the development of sustainable practices and on ensuring that further human impact on marine ecosystems is minimal.

To respect marine life, pay attention to the fish in every imaginable shade, the electric blue angelfish, and the kaleidoscope of marine life in coral reefs as they respond to stress through hiding, changing colours or trying to swim away from you. The stress is a signal for the photographer to take the hint and move away from the subject.

Use natural light

UNEP science shows that artificial light affects turtles, seabird feeding patterns, reproduction, migration and predatory-prey interactions. So, when underwater, use natural light sources: the moon and sun. That can create stunning visuals and enhance the authenticity of the underwater scene. Make sure to position yourself appropriately to capture the best lighting conditions and adjust the camera settings accordingly.

Don’t touch corals

Diving practices play a crucial role in sustainable underwater photography. Follow responsible diving guidelines by maintaining proper buoyancy control and a hands-off policy to avoid damaging delicate marine ecosystems.

Make sure your fins and other body parts are not touching your surroundings. The photographer’s movements can accidentally damage coral reefs through smothering.

The collapse of coral reefs, which is being driven by climate change, has far-reaching implications for the entire ocean and for people. Reefs are considered sentinel ecosystems that protect 25 per cent of all marine life and support the livelihoods of coastal communities.

Carry appropriate equipment

Equipment for underwater photography has evolved not only to become more accessible but also more advanced. When selecting underwater photography gear, opt for equipment that minimizes impact on the environment and is more agile and easy to carry while maintaining good dive practices.

Regardless of what camera one uses, it is crucial to have good water skills. It would be counterproductive to use a camera set-up that makes you uncomfortable and unable to control your body position, that can end up causing damage to the marine environment.

Use your images to raise awareness

Underwater photography is a unique opportunity to raise awareness about marine conservation issues. Through informative captions, a photographer can highlight the radiant colours of coral reefs as a reminder of the fragile balance of life beneath the waves and urge humans to cherish and protect these magical ecosystems for generations to come.

Dive photographers can use their social media platforms to educate audiences about sustainable diving and the importance of protecting marine ecosystems to create a positive impact beyond your photography.

About World Oceans Day

UN World Oceans Day reminds everyone of the major role the oceans have in everyday life. They are the lungs of our planet and a major source of food and medicine, and a critical part of the biosphere. The purpose of the day is to inform the public of the impact of human actions on the ocean, develop a worldwide movement of citizens for the ocean, and mobilize and unite the world’s population on a project for the sustainable management of the world's oceans. UN World Oceans Day 2023 is hosted by the Division for Ocean Affairs and the Law of the Sea of the Office of Legal Affairs.

About The Reef-World Foundation

The Reef-World Foundation is a charity that leads the global implementation of UNEP's Green Fins initiative, which focuses on driving sustainable scuba diving and snorkelling worldwide.
