With the sun set for the day, the crowds along Darwin's shoreline had begun to go home, but some people stayed to enjoy the 'blue hour', a time when the sky provides some magical colour - if you keep an eye open for it. Or a lens….
This image is a composite of three images made while the camera was on a stable tripod, with each image being quite a long exposure, and then processed in Aurora HDR software.
The effect of the long exposures is to render a silky smoothness to what was actually a slightly choppy sea.
The blue hour is a great time for photography - different that the golden hour that occurs on the other side of the sun rise/set, and shooting both can provide some interesting variety in the space of a couple of hours.
