Westminster has been the source of much anger recently following the Brexit referendum but Jorge Otero-Pailos’s installation The Ethics of Dust (until 1 September) invites long term contemplation of the momentous decisions that have taken place here. Organised by Artangel and on show in Westminster Hall, the artist’s translucent 50-metre-long latex cast has captured the dirt and dust that has accumulated here over the centuries.
None of Georgia O’Keeffe’s works are held by a public institution in the UK, so Georgia O’Keeffe (until 30 October) at Tate Modern is a rare opportunity to see many of the influential US artist’s pieces. Among these are her most famous flower paintings as well as lesser-known abstracts such as My Last Door (1952-4).
Sickert and Photography (until 17 April 2017) at Tate Britain is a small display, which opened this week and looks at Walter Sickert’s use of the burgeoning medium of photography as a direct source for his paintings. The artist produced his own photographs to copy from, including a series in which he posed as Lazarus. He also used images taken from newspapers that on one occasion led to a plagiarism spat between him and a photojournalist, which is played out in the Daily Express newspaper clippings accompanying the exhibition.
