Here is a photographic journey along the 215 miles of the River Thames from its source in Gloucestershire to the mouth, first travelling along the north bank & then back along the south bank. The journey takes the reader through Gloucestershire, Oxfordshire, Berkshire, London & out into the Thames Estuary where the river meets the North Sea. Photographer Stephan Kaluza & his assistants made their journey partly on foot & partly by boat & took pictures of both banks every few seconds, culminating in about 30, 000 images. A selection was then digitally combined to form the long consecutive sequences of the astonishingly changing & varied river banks, whether the green fields of the Cotswolds, the university spires of Oxford, the boathouses of Henley on Thames, or the built-up areas of London, from Battersea Power Station & the Palace of Westminster to Tower Bridge & Canary Wharf, or the industrial areas towards the mouth.
