ambiguity

Deciding on a category for this one was difficult. I've had it for a bit, but haven't put it up.
Stare at this for a while... there's alot to see.
Of course, it ceases being ambiguous once you're positive what it is, but this was taken across the street from Sutter's Fort on a walk of mine.
I'm rather fond of this... photo editing minimal. I purified the black and white (although it was essentially this color scheme to begin with) and added text.
