"Rain on the Studio Window" exemplifies Hockney’s manner of juxtaposing oversimplified line and color with complex yet subtle textured patterns. In the creation of this still life, Hockney’s choice of using an iPad reflects the artist's integration of technology, as he is better able to color-match tones. Thereby, the artist presents the viewer with an image that is closer to the perceived world than if it had been captured with a camera.
