The Thames has been the meandering spine of London for centuries and it is on the banks of this iconic river that London was built. I had been observing and studying the tides of the river to be able to capture the city at various locations at the right time. On this day, I was surprised to see how calm the river was - I had never seen it so still. I feel lucky to have been able to capture Westminster Bridge and Big Ben, two of the most recognisable icons on London, on that day.
