I kept seeing posters for Hockney's "A Bigger Picture" show whenever I used the escalator on the underground. Every time I looked at it I felt a bit depressed.
In 1964 Hockney claimed he felt he had to get away from England because he felt it was grey and dreary and, in order to be inspired, he needed to have the space and light you get in California.
All these decades later David Hockney now delights in being able to see the beauty he missed in his youth and says the landscapes in Yorkshire give him a "spatial thrill." He's also a man who loves his iPad...
Hockney: "What's really good about the iPad is it's speed. No other medium using colour is as fast, meaning you can capture quick lighting effects like nothing else. The spring is just spectacular this year, and I am getting it down."
This time round, the paintings - some of which are 6 meters long - have to be seen to be believed and the postcards can't capture their power.
