I wanted to take some photographs of the the Palace of Westminster at sunset having noticed that the sun sets directly behind the Palace and so studied the Met Office to see when sun set occurs. Thinking that was actually the time of darkness, we got there early to catch the sunset and set up my tripod and waited and waited and waited and 6.10 p.m. came and went and it still wasn’t anywhere near darkness. Lesson learned darkness occurs half an hour after sunset, well in this country at least. By the time we had finished and had taken some photographs in the dark as well, we were properly frozen. But it was worth it.
