“I’ve always been drawn to coral reefs,” says Douwma. “I’ve photographed them for as long as I can remember. To watch them die would be a tragedy.” But that’s precisely what’s happening to reefs worldwide, as a result of global warming, ocean acidification, and pollution of marine habitats. In the past three decades alone, around 50% of corals have been lost, with the latest forecasts suggesting that over 90% of reefs will be gone by 2050.

Looking for a way to develop her work in new directions, Douwma began experimenting with what she calls ‘coral kaleidoscopes,’ creating arresting compositions with strong symmetry, texture and design. “My ultimate aim is to capture something that is greater than the sum of its parts,” she says. “Something that can communicate the vibrancy and colour of healthy reefs.” The resulting pieces bring to life in spectacular fashion the underwater edens that we stand to lose, unless we can find a way to reduce negative human impacts.

To be mesmerised by more of Douwma’s coral kaleidoscopes – and find out how her images mirror the work of scientists racing to save coral reefs from extinction – read our full story here.
