Guided by renowned underwater photographer and conservationist Paul Nicklen, Neon Nights illuminates the secret world of biofluorescence beneath the ocean's surface. At night, using blue-light torches and yellow filters, coral reefs and sea creatures burst into neon greens, oranges, and reds—revealing vibrant forms of life otherwise invisible to the human eye. The film explores how these fluorescent displays provide insight into marine biodiversity and underscores the urgent need for marine conservation in a rapidly changing climate.
