In the foreground, I used the flashlight to "paint" the hexagonal salt, crystal-like pattern on the ground.
You have to find a right setup with the manual mode. Because it's dark, the camera won't focus with the auto-focus. You can use your flashlight to manually focus your camera to about 1/3 from the bottom of the picture. You really need to play with ISO and aperture. I like around 400-800 on ISO and 4-8 on aperture.
I broke my lens protector filter, dropping my camera in the dark, but this was worth it. I wish I did longer exposure for trails of the stars. (Nikon D800E, Nikkor 16-35 mm, ISO=400, RAW, 10 minute exposure, foreground artificially painted with a flashlight, tripod, f/4)
