David Hockney's art in the 2000s is a testament to his enduring creativity and willingness to explore new mediums and themes. Throughout this decade, Hockney continued to engage deeply with the landscapes of both Yorkshire and California, utilizing his sharp eye for detail and vibrant color palette. One notable work from this period is "The Gate" (2000), an oil on canvas that highlights Hockney's skill in capturing the essence of his subjects through color and composition (Hockney). During this time, Hockney also embarked on an ambitious project that explored the use of optical devices by the Old Masters. He began writing a book, "Secret Knowledge," which detailed his research into how these artists may have used lenses to project images onto surfaces, which they then traced or adapted to create their masterpieces. This project included creating "The Great Wall," a visual chart in his Los Angeles studio that mapped five centuries of Western artistic development, showcasing Hockney's deep interest in the intersection of painting and photography (The David Hockney Foundation: Home). Hockney's exploration of digital mediums also took off in the 2000s, particularly with his adoption of the iPhone and iPad as tools for creating art. He produced a series of digital drawings, including many self-portraits and floral compositions, which were later exhibited and highly praised for their intimacy and immediacy. His "iPhone Lilies" (2009) and contributions to "The Yosemite Suite" (2010) stand out as examples of how Hockney embraced these new technologies to continue his exploration of domestic themes, landscapes, and the nuances of daily life (TheCollector). These works from the 2000s not only underscore Hockney's versatility as an artist but also his continued relevance in the contemporary art world. Whether through traditional painting, digital drawing, or rigorous art historical research, Hockney's work during this decade reflects a deep engagement with both his subjects and his mediums, revealing an artist ever curious and ever evolving.
