When David Hockney discovered the iPhone as an artistic medium, it opened up entirely new possibilities for his art. He made his first digital drawings in spring 2009, describing the morning landscape in broad lines and dazzling colors directly on a display that offered subtle hues as unmixed expressions of pure light. Then in 2010, Hockney started working with an iPad, and the larger screen expanded his artistic repertoire and enabled an even more complex interplay of color, light, and line.Each image in this book captures a fleeting moment seen through a window in Hockney’s Yorkshire home: from vibrant sunrise and lilac morning sky to peaceful night-time impressions or the sudden arrival of spring. Fascinating details reveal drops on window panes, distant lights in the night, reflections on vases or an abundance of varied window-sill vegetation. In 120 drawings made between 2009 and 2012, selected and arranged by the artist himself, we experience the passage of time through the eyes of David Hockney.This artist’s book, which first appeared in an exclusive signed edition, now returns as an unlimited run, whose still generous XL format presents Hockney’s impressions in brilliant resolution. So now is the perfect occasion to heed the advice of the Times critic regarding this book: “If you would like to be given a bouquet by David Hockney, here is your chance.”
