Cargodna, so it was always in the back of my mind to make use of the photographs I took that day. This is actually based on a shot taken from my painting position - it's just a wider view, incorporating another of the Wheal Owles engine houses. And a gate. Not to mention the memorial stone for the accident (in the foreground; it's a chunk of granite with a small plaque on the other side of it).
This time, I used a dark underpainting on the engine houses, with the intention of increasing the definition of the stonework; I think it worked. And, of course, one of the benefits of working from a photograph is that the light doesn't change...
You can see the underpainting (as well as my original Cargodna painting) in these in-progress shots:
