Edit: I've swopped the original square crop version of this photo for the unaltered 3:2 format that my camera produced as I prefer the top of the sky which is visible in this version.
The unusual light is a product of the stormy weather and the long 3 minute long exposure.
It was very windy on the coast with storm clouds rapidly moving in from the bottom of the frame and obscuring the lighter clouds higher in the sky to give this unusual effect.
When we were kids we used to swim out to this marker - not something I'd try these days even though the Mersey estuary is a lot cleaner these days.
