I grew up in Bangor, so the sea-front, the piers and the area surrounding it were the background to my youth.  Just beyond the North Pier is The Long Hole, a sea inlet, into a  rocky narrow pool, quarried out from the rocks in the 19th century, with man-made slipways and walkways.  The Long Hole is now disused as a harbour.

It was around 8pm in September 2018 when I visited, and sunset was just 30 minutes later.  Still there was enough light to shoot at ISO1600, f/4 @ 1/60th sec, the Fujifilm X-T2 handheld.
