This was an incredible experience on an August night on the coast of Maine! The blue light is bioluminescence, emitted from microorganisms in the water as the waves wash them over the rocks. While the glow in the photo is brighter and much more blue than it was in person due to the limitations of human vision, and the fact that the camera can see more with long exposures, it was still intense to see in person and the photo doesn’t do the experience justice. The blue light is real, and is just about how my camera captured it, I didn’t do anything to boost the blue. My night vision was adapted enough to see the bright glow in the water as the waves washed over rocks but only as white light.
This is a blend of 10 exposures for the sky and 2 foreground exposures. 10 shots for the sky were each taken at ISO 10,000, 10 seconds, f/2.8, and then stacked with Starry Landscape Stacker for pinpoint stars and low noise. The 2 foreground exposures were taken at lower ISO and longer shutter speeds for a cleaner foreground, 1 at ISO 1600 for 20 minutes and another at ISO 6400 for 2 minutes, both at f/2.8. The exposures were then blended in Photoshop to create a single image with low noise and sharp focus. All shots were taken with the Nikon D810A and Nikon 14-24mm f/2.8 lens at 14mm.
