Photo of Op Artist Bridget Riley in the mid 1960s by John Goldblatt.
"Riley had great freedom as a child and spent a lot of her time playing on the cliffs and beaches near Padstow where she lived. She spent hours watching the changing light, colour and cloud formations and stored away what she saw in memory. She has later said that these early memories have had a big impact on her visual awareness throughout her life." —Op-Art.co.uk
