The Royal Watercolour Society (RWS) annual Autumn exhibition, featuring works in waterbased media on paper.
This year's theme is The Shapes of Water:
"The Shapes in water are what watercolourists work in. Watercolour’s great complication is its transparency, challenging every aspect of the artist’s skill. In their pursuit of capturing form, many artists build thick layers of waterbased paint, while others hint at shape with indications of colour applied in broad washes. For more than two hundred years the RWS has represented the very best in water-based media on paper and to this day artists continue to push at the limits of this unpredictable medium and its capabilities." - Charles Williams PRWS
