One exposure. Taken inside of the Custer State Park in SD around midnight. I scouted the spot earlier in the day and went out at night to capture this image. I heard a car driving through the park and at midnight, I knew I wouldn't have too many chances inside the park. Once it came around the corner, I captured a 20 second exposure so the car's headlights lit up the trees throughout the image. Fuji Xt2 with 16-55mm at 20 seconds.
