It's odd, but when I find something on the beach that I think is worth photographing I very rarely disturb it, and often come away having very little idea about the object itself. Take this shot: it's the side of an upturned tin, about 4" in diameter, part-buried in the sand; but I have no idea what it once contained. And I'm not sure why I don't move them or examine them – after all, they're little more than discarded rubbish – but there's always something that holds me back. Maybe it's something to do with thinking that if I think it's worth photographing, it's a scene that shouldn't be disturbed. I don't know.

So, here's what may have been a biscuit tin, a tin that contained a 'boy racer' mug, or maybe it held something different entirely.
