An impressive sunset after a dull, grey day.
I have seen it many times: at the very end of the day the sky clears out. So it is always worth waiting that little bit longer. Don`t go home too soon!
I'm planning a trip up north for next month if everything goes according to plan I will spend a couple of days up there... I don't know where you are based but I'm meeting with other photographers based in Belfast it might be an idea to get a evening out by the causeway or something...
