Saw the lightning storm and tried my luck. Got lucky.

The boat shed was beilit by some very yellow/orange street lights. If I set the white balance right on the boat shed the background was extremely blue. I know it’s still kind of blue but that was an artistic choice. I had to select the shed and walkway and colour balance them separately. The ripple on the right side was caused by a dolphin swimming right under the camera (and scaring the sh1t out of me). 25 second exposure, f11.
