This blue hour image highlighting the iconic Sydney Opera House and Harbor Bridge is a five shot pano taken from the north side of the Sydney harbor near the Luna Park amusement center. There were no clouds that evening so the sky and sunset weren't very interesting, but there was some great blue hour light that contrasted nicely with the city lights.
Nikon D7100 and Sigma f1.8 18-35 at f/11 and 8 seconds for each shot.
