David Hockney has been painting on his iPhone and iPad for a couple of years now. He’s finally decided to exhibit the work and Martin Gayford is helping him out in the Telegraph:
The novelty of what he has been doing is two-fold. Firstly, this is a new medium with fresh possibilities, requiring unorthodox techniques. Hockney executed the drawings mainly with the edge of his thumb; you can’t use the thumbnail, he says, because
the device is sensitive to heat, not just touch. The second innovation is in the method of distribution. He sends these techno-sketches out to friends, who may then pass them on, collect them or do whatever they want.
Each image as it appears on another iPhone or laptop is virtually identical to the original, although Hockney points out that even with a manufactured item such as this, there will probably be minute differences. Even so, the drawing on my phone not only looks like the one on his, digitally and in almost every respect it is the same. This is profoundly subversive of the art market as we know it, with its focus on the signed original work.
