I started with two panorama shots of Boston, from the other side of the Charles River (by the MIT campus). They were taken from the exact same spot, one at night and one during the following day. Each was a 10-shot pano at 70mm in portrait orientation (1D X, 24-70L II), although I cropped them to ~7 shots worth for this, so I could pick ends where the buildings lined up nicely. There were a few boats floating in the foreground, and I cloned those out (including the masts among the buildings). Then I converted both night and day panos into tiny planets, cleaned up the seams, pasted the day planet over the night planet, and applied a gradient layer mask.
