Don’t take things for granted. There are photo opportunities in every city if you can focus on what is a contrast to another region or country. Look at the architecture, the cityscape, the air quality, the cars people drive, how they dress, and more.
As with many walkabout photo grabs, I worked first get real clarity and shots of my subject material. In the editing session I noticed that the resolution was so high on a lot of my museum shots they were almost too difficult to examine for uniform tones and deep and near/far crispness. But cropping the sides of the shot generated a lot more visual drama inside the frame. The “forced” intersection of the vertices of the vaulted “flying buttresses” to the near wall created a perspective repetition of the arched “tunnel”. Certainly the word “cathedral” came to mind many times. But the image files allowed me to convey the excitement the grandeur of the structure created in me.
