The photos exhibit time and motion though the rising and falling tides of the Thames River.  On the 25 of May, there was a New Moon which created a forceful gravitational pull of the river causing very high and very low tides.  On the majority of days, there are two high tides per day and two low tides per day.  There is approximately a 7 hour difference between the two extremes.  The exhibit is comprised of three series of photos demonstrating time and motion through different approaches and styles.
