The Durand-Ruel exhibition at the National Gallery ends on Sunday but is a must. There are some rather soupy Renoirs, however these are offset by the glorious paintings by Monet, Pissarro and Manet, also some superb blown-up black and white photographs, in particular one at the entrance to the exhibition of the Durand-Ruel gallery in Paris which makes you feel you are standing in the street looking over the road. Meditation: Madame Monet on the Sofa was painted by Monet in 1870 when he was thirty. The painting is normally at the Musée d’Orsay; but in London until Sunday.
