Near to Brick Lane, a railway embankment formed a blank canvas for the graffiti artists' expressions. It appeared to be a known and accepted venue where you can watch them at work. There seemed to be some kind of loose arrangement of divvying up the walls between different artists, and some of them were encouraging passers-by to add to the work with a spray can.
I wouldn't normally dare to photograph anyone painting graffiti (mainly for fear of the spray can being turned on me!)
Here, they seemed to welcome being watched and photographed. I enjoyed the verve and energy of the guy who was working barefoot
