"Tide's out" is self-explanatory, but the "so are the fires" probably isn't. It refers to the structure at the top right, which is the now closed Longannet coal-fired power station.
C&C are always welcome but I'd especially like some feedback on this one: it was shot using the 14mm lens and the B&W conversion is rather more, shall we say "dramatic" than is my usual taste in these things.
