I'm a bit embarrassed to say that this image was really a throwaway. It has never been edited.
We just arrived in Rome in 2018 and wanted to do some test shots. Captured with the iPhone 6 on the balcony of our hotel. Sometimes the more popular images are the ones I've ignored. As of this writing, this image has been receiving quite a few favorable responses in Instagram. While my favorite ones are the ones that most people hardly notice. I can't figure that out.
