857-94843 - The original lighthouse at Cape Spear in Newfoundland sits dark, with the new lighthouse nearby. The original lighthouse started operation in 1836, and in 1955 a new concrete light tower was built. The original lighthouse has been restored to the period of 1839. This was tricky to shoot because the green light of the active lighthouse would flash every 7 seconds and wash out the scene in intense green. I didn't like the harsh shadows from the light, myself and my tripod being one of them, so I took a bunch of 6 second exposures and used stacking to get pinpoint stars and low noise in the sky and foreground. Nikon D5, Nikon 14-24mm f/2.8 lens @ 14mm and f/2.8. Six shots with the ISO between 12,800 and 25,600, as I was playing around with the camera to get a feel for its performance, stacked in Starry Landscape Stacker for Mac.
