I took an ulmost identical shot to this using my four-thirds camera last year... But I was in the neighborhood again and with little else to take apart from wall after wall of rubbish graffiti, thought a reflection shot of the P&G plant was worth repeating...
Had a some friends over in the evening for some fine food and chat - and before we knew it, plans for a visit to Brick Lane had been organised for the next day with me leading the way... Easy Peasy :-)
