This was a perfect sunset for displaying the subtle shades of twilight.

On this evening the sky over the ocean showed off the classic sunset gradient from deep orange though yellow, purple and into deep twilight blue. I shot this on the water on my cruise around the Whitsunday Islands on board the Solway Lass. Note the dark reflections of clouds in the water.

We’re looking west, of course – the Sun still sets in the west in the southern hemisphere! – which is back toward the mainland of Queensland, Australia.
