1. Eyewitness: Hungarian Photography in the 20th Century, is at the Royal Academy until Sunday - I wrote about it here.
2. Also closing Sunday is Richard Dadd at Orleans House Gallery (pictured), Twickenham, a fascinating little show of the patricidal Victorian artist's work from the Bethlem Royal Hospital Collection.
3. Due to end 2 October but extended for one more week is another small exhibition: Frida Kahlo & Diego Rivera at Chichester's Pallant House Gallery. It features a few of her most iconic self-portraits and some beautiful colour photographs of Kahlo by Hungarian Nickolas Muray.
