Worth a visit
This landscape was originally a mine and was recovered and turned into a sculpture of a woman, perhaps the largest in the world.
These are pictures I took of a treehouse using my canon and a 50mm lens. It was a sunny day and the light was very good so I could take advantage and use a F22 aperture to make the picture sharp. Treehouses are regarded as eco-friendly because you don’t need to clear the forest and you can use sustainable wood. They also have the advantage of being high up enough to avoid dangerous animals although I doubt this is usually a problem in Northumberland.
