I've always loved ruins. If you were to ask my parents, they'd tell you that I've always strongly preferred English Heritage properties (typically falling down) to nicely-preserved National Trust houses.
I think it's partly about letting my imagination take over, but one part of what I love about ruined buildings - especially large ones - is the range of options for framing scenes. Windowless windows, door-free doorframes, and tumble-down walls all provide interesting outlines for beautiful pictures.
In Derbyshire this weekend, we enjoyed visits to two different English Heritage houses - Sutton Scarsdale Hall and Bolsover Castle - which both have significant ruins. I'll post a little more detail shortly, but for now, here's a selection of fun framing shots.
