Three pictures - one afternoon

I took these pictures the same afternoon as those in Trafalgar Square. The first is a lady in the entrance of The Photographer's Gallery in Newport Street. I loved the overall shape and the interaction with the ladies outside.


The next was in Trafalgar Square, and is a notice outlining all the rules and regulation that apply, typically done in a way that no one actually sees them! apart from some wit whose comment is a non-sequitur, or maybe I am not on the right wavelength!?


Finally on a wall leading to a private mews in Knightsbridge a shadow of a hedge on a white wall.

Isn't the sheer disconnectedness of these images all taken within a few hours what makes photography so addictive?
