The five sketchbooks from this German tour that Turner filled with are evidence of extremely hard work: day after day spent tramping up and down hills in search of good viewpoints and interesting subjects. This , looking down on to Huy, shows Turner developing one or more of these
sketches drawn from vantage points
found in this way.
Bodycolour (or , its French name, from the Italian aguazzo – meaning mud) functions a bit like oil paint. Here Turner mixes increasing amounts of white into the pigment to achieve the lighter , with pure white for the highest lights.
