A cave diver is silhouetted against a colourful backdrop in cenote Chikin Ha. “The caves in the Mayan riviera have amazing chambers with pristine formations that have been preserved over millennia,” says photographer Martin Broen. “Tannic acid created by the decomposition of organic matter accumulates in the upper part of certain caves and modifies the colour of the light passing through based on its density, giving the surreal feeling of flying within a rainbow.”
