Wild and crazy architecture

This is one of the most unique architectural designs in Europe. It is in the city of Zaandam, Holland. It is great to photograph any time of the day, even midday, but my favorite lighting for architecture and cityscapes is dusk and twilight when the lights of the buildings mingle with a beautiful sky. I did three things in Photoshop to this picture. First, the original sunset sky was good but not great, so I replaced the sky. Second, because I used a 16-35mm wide angle lens to take the shot -- and the camera was angled upwards somewhat -- keystoning resulted. In other words, the vertical lines of the building leaned inward. In most cases, I correct that. To do that, I selected the entire image with Select > all and then chose Edit > transform > distort. Handles formed around the picture and I dragged the upper left and upper right handles until the vertical lines of the architecture were, in fact, vertical. Third, I used 'generative fill' to eliminate a few people in the scene. My settings were 1/60, f/4.0, 3200 ISO
