A traveling amusement park occasionally stops in our town. They set up in the local mall parking lot. This photo was taken from the roof of the parking garage one night.

The challenge was to find settings that would blur the moving rides and not overexpose the stationary signs. Then I had to wait until all three rides were going at once.

Shot with a Nikon D750. f/29, 2 seconds, ISO 50 and -3 steps exposure compensation.
