Measuring 37" x 28", Yosemite No. 21 presents a vivid and abstract interpretation of Yosemite’s landscape, where undulating hills and valleys are depicted in vibrant greens and yellows. The piece is distinguished by Hockney's playful use of lines and patterns, which suggest the natural contours of the terrain while infusing the scene with a sense of movement. The dark shadows and highlighted areas create a striking contrast that guides the viewer's eye through the composition, evoking the depth and grandeur of the landscape. This work exemplifies Hockney's unique ability to transform traditional subjects into bold, contemporary art through his innovative use of digital tools.
