My wife and I had a surreal day ambling among the gypsum sand dunes at White Sands National Monument this past spring. It really is a special place, especially if you hike a bit and find your own solitary oasis. Which we did, barefoot of course!
I captured the image above with a Nikon D850/Nikon 18-35mm @ 35mm. I increased the exposure by +0.3 via the exposure compensation button (a handy button every photographer should be using in auto exposure settings), which elevated the total scale and prevented underexposure due to the brightness of the white sand.
