As the light fades the length of exposure increases which makes for some fun photography when there are moving objects (or people). I generally take a tripod when I go to Southport Pier so that I can get everything just right, it also means that I can capture moving walkers as the sun sets.
The Southport Pier sunset changes with the time of year, and at this time of year the sun is a little too far south to be spectacular, but I think it was still worth grabbing the shot!
