I was struck by the similarity in the expressions of the three people in this photograph and by the variety of interactions.
There is interaction with a paper map; there is interaction between two people, and there is interaction between the woman in the foreground and her camera display.
The headstone you can see between the man and the woman is that of Greyfriars Bobby – the little dog that stood by the grave of its master for 14 years after his master died, leaving the graveside only to get food (and to write his blog about his adventures).
Panasonic GF1 and 20mm lens. 1/320 second at f5 and ISO 200.
