Basically, painting is idiocy,” the German artist Gerhard Richter once said. In a poll by Vanity Fair to find the greatest living painter, Richter came first – not bad for an idiot. Now 87, his works have made him a multi-millionaire but delve into his world and you will be surprised by the methods that have delivered this fortune, especially the use of a squeegee loaded with paint and rubbed and scraped over photographs. Richter, who experiments endlessly with method and materials, often uses photographs as source material.

Among his oeuvre is a celebrated body of seascapes in a range of formats and styles painted from the 1960s to 1990s. In the earliest, the sea and beach are a mere backdrop for portraits taken from family photographs. This is the largest number of Richter’s seascapes ever assembled, allowing undistracted study of this particular stream of his work.
