We were sailing from Alta, Norway, inside the Arctic Circle, and most of the guests on board had stayed up past midnight in the hope of catching a glimpse of the dancing night sky. The open decks were quiet, and the air was calm, almost eerie. The bridge had dimmed the outdoor lights on the ship, and those along the bow had been turned off.

We stood waiting patiently for the atmosphere to change and didn't wait long. Within minutes, gentle, grey, mist-like clouds appeared across the sky, moving erratically in every direction. The colours weren't visible to the naked eye, but once you looked through the lens of a camera, there it was. A bright green hue rolled through the air as if dancing to the soft beat of a drum. It was thrilling; I didn't know in which direction to look. This wasn't the first time I'd been fortunate to witness the Northern Lights, but it was certainly a moment that has stayed with me.
