Royal Scottish Society of Painters in Watercolour (RSW) 6th Open Annual Summer Exhibition, Lillie Art Gallery, Milngavie. Glasgow, until September 27

THIS is the second time which the Royal Scottish Society of Painters in Watercolour (RSW) has travelled to the Lillie Art Gallery in Milngavie to stage an exhibition. Featuring over a hundred works painted using a water-based paint, there's a wide array of work, ranging from landscape to still life to abstract. Prepare to be assailed by a bravura mix of approaches to this most difficult – and occasionally unforgiving – of mediums from some of Scotland's grand masters of the art. Into this, add a smattering of emerging painters making their mark.

Names such as Glen Scouller and his wife Carol are represented. Both dab hands at watercolour and possessed of instantly recognisable but very different styles. Dawson Murray's Lotus Pool is another gem which glows iridescently; all deep blues and vivid emerald green.

There's an intriguing triptych from Janet Melrose called Earth Works, which consists of three pale yet pulsating circles and two deftly executed life drawings on what looks like hand-made paper by Lin Chau.

Watercolour lends itself to large sweeping semi-abstract landscape and RD Murray's North Sea is a belter in that direction. As is Joe Hargan's West Coast.

Ann Oram's painting Field Edge with Cow Parsley is the poster image for the exhibition and a stand-out example of what can be achieved with water-based paints. Oram will be giving a demonstration of her painting techniques, on a large scale and on the floor, tomorrow (Saturday) at 2pm. Jim Dunbar will give a presentation of his techniques for painting out of doors next Saturday, September 2, at 2pm.
