Ancient symmetry

These are the ancient baths in the Alcazar in Seville, Spain. They were built in the 12th century. I shot this with a 16mm focal length on a 16-35mm lens, and in post-processing I enhanced the saturation of the colors. It was quite dark in here as you can see from the camera settings -- 1/60, f/4.5, and 8000 ISO. I eliminated the noise with Topaz DeNoise AI. In a shot like this, you have to make sure all the elements are balanced perfectly. In other words, the symmetry has to be as perfect as possible. You have to stand dead center when shooting, the horizon line (imaginary in this case) has to be exactly level, and all the elements on one side have to be mirrored on the other. With a wide angle lens, this takes a bit of practice and a critical examination of the image in the viewfinder.
