Late evening twilight by the river in the Demesne.
This picture is a bit fuzzy because the light was much dimmer than it looks, and the shutter speed was slow.  It shows Diane and Lord Rosse on our second encounter with him.  He was pruning the bush he's facing here -- a "strawberry bush" -- which he had planted next to the river to test an idea about the role of reflected light from a body of water on the growth rate of that particular bush.  He and Diane hit it off on this interchange pretty quickly, and our invitation to visit him and Lady Rosse in the castle came from this little encounter, I think.
