In reply to Jim Haydock: Thanks Jim. Close, it's the B&W 10 stop ND
I think the Jetty is close to the Ashness bridge car park a long the right side of the lake on the B5289. The panorama is about 200 metres further round the lake, you can see the jetty from the first shot at the edge of the frame. Probably not worth taking a long trip to Seascale just for photographs, I visited there because I felt like a day at the coast.
Completely agree about the lighting. No matter how good/bad the composition is, the right light is what makes the photo... I just wish I had more motivation to get out of bed at 5am to catch it
