This band stand in Forest Park in St. Louis is a gem among other landmarks in the park where the 1904 World's Fair was once held. This is one of my more laborious attempts at blending blue hour artificial light with the ambient light from sunset. Not bad for a random trip to StL to get a sunset like that! Unfortunately, a duck swam across the pond during the best light. To bring back the crisp mirror-like reflection in the water, the lower half of the image is from a later moment in time. To keep some consistency in the reflection I inverted and blended in parts of the upper half of the image (clouds and parts of the band stand).
Main settings using a Nikon D3200, 18-55 mm and a polarizer were 22 mm, 1.6 s, f/11, ISO 100
