The Eiffel Tower at night offers a multitude of photographic opportunities. The beam of light that rotates around the top of the tower presents a unique challenge in that a long exposure is out, if you want to capture that beam of light.
For a low noise image at ISO 100, I selected the widest aperture and the shortest shutter speed that would expose the image properly.
