The Earls of Egremont at Petworth were renowned for their patronage of artists and creative craftsmen who have left a host of treasures.

Today the estate is administered by the National Trust, who restore and conserve one of Britain's richest art collections. Bernard Price and Richard Cusden tell the story of Petworth and its pictorial heritage with music from Close Harmony.

Her dazzling patterns and waving lines of colour have created a style that is unmistakably BRIDGET RILEY. As Robert Hughes commented in The Shock of the New, 'What seem, at first, variations of a "mere" pattern turn into metaphors of unease, uncertainties tuned with an exquisite poetic skill'.
Bridget Riley has become Britain's leading abstract artist and this month she is holding not one but two exhibitions, her first in London for five years. In this film she talks in her studio about why she paints and the way she paints-finding out what the eye can see, exploring what looking actually feels like. 'Looking', she says, 'is a pleasure - a continual surprise '.
