There has been a bit of a fashion lately for shows where an artist’s works are projected at huge size on the walls and floors. The Hockney one at Lightroom (‘Bigger and Closer, not smaller and further away’) is the first I know of where the artist is alive and actively involved in the show. Hockney, of course, has always been up for using technology, whether cameras or more recently iPads.

This show amounts to a guide or commentary to all the different periods of his career, narrated by the man himself. I thought a few things worked particularly well – watching the construction of some paintings, joining in his ‘Wagner Ride’ and animations of his set designs (he has apparently suggested the Lightroom set up could be used to stage a short opera).

It’s lucky that Hockney is good at explaining his views on perspective, say, or the representation of time. He tells us how much he liked it being always warm and sunny in L.A., but he also says there is no bad weather. (‘If it’s raining, I’ll paint the rain: if it’s snowing, I’ll paint the snow. All of the world is beautiful, really, but people don’t look at it.)
