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.
