At the time I thought this was some sort of shopping centre or cinema complex, as I recognised one of the restaurants on the ground floor of the building. It turns out it was a Casino. As you can see it was a very calm evening in Glasgow and the River Clyde was very still. This allowed for a mirror like reflection when captured with the right shutter speed. The above capture was originally intended for HDR (high dynamic range) processing but in the end I preferred one image over a combination of different exposures.
