This was the second time I have been on this roof, which is on an old mill in Bolton. I have an idea for a photograph and this was the first attempt. I love the reflection of the sky in this large puddle of water. I really need to get much lower with the camera angle and I would ideally like more of a blue (with a few clouds) in the sky. Since taking this picture I have been back on the roof when the sky was perfect, but the roof was dry as there was no rain the few days before the lovely lighting. I will keep trying.
