I went to Tate Britain today to see the McCullin exhibition. It took over an hour and three quarters to see everything.
Time well spent. Highly recommended with the proviso that if you are easily upset by warzone imagery then you should not go.
One of his landscapes had me mesmerized. So much so I ended up buying the book just to have a copy of it.
I had a wander along the Thames afterwards and ended up at Trafalgar Square.
