Variations in the night sky

I have been photographing the top of the Empire State Building for a project I am doing to combine all of its color variations into a mosaic. Trying to achieve some variety in the same exact subject in similar circumstances can get to be a bit of a challenge. Incorporating the current weather phenomena helps to differentiate the shots.

Here are several I did over just the past few nights. All taken with the Fuji X-Pro2 and 16-55mm f/2.8 lens.

The Empire State Building lit up in Easter colors over the weekend. This is a straight shot combined with a time exposure of the blurred clouds. 

This image is a triple exposure combining a straight shot of the building with an out-of-focus shot, and then a lighter version for the moving clouds.

This is a single long exposure of 30 seconds to capture the fast moving clouds. A 9-stop ND filter was used to allow for the long exposure. 

Simple straight shot at dusk with moody clouds passing by. 

Double exposure of the Empire State Building combined with an image I took earlier of its facade reflecting the setting sun.
