Variations on a theme

I set out to capture a black and white version of a scene I had done before of the Empire State Building framed by the Manhattan Bridge.  I ended up taking several variations of the same situation as the light changed from sunset to evening.

The night scene photographed with the Nikon 80-400mm lens at 380mm on a D800.

The same scene but photographed earlier and in color with a longer 550mm focal length.
