An open day at Pitstone museum, although quite dark inside, this old barn had some great directional light coming in from a side door. I had to wait until the blacksmith was facing the right way towards the light, and then waited some more for the right hammer action.

Converted to monochrome in Photoshop, with my favourite chocolate effect.
