Thanks for this. It is one thing I really want to try my hand at. For a variety of reasons, I've not been further than seven miles from my house in the last two years, and there is a limit on what you can find to take pictures of that is new. However, with some work I've had done to the house, the view has come to me so I will experiment with some long exposure photography - especially as I've just found my tripod again.
