In the 1960's English painter, David Hockney fell right into Pop-Art. His work that initially took off was not his paintings, but photographs. 
While other artists used fish-eye lenses and similar tricks to take pictures of an entire room (in order to paint it), Hockney disagreed with this practice, as the image that resulted was warped. Trying for a more realistic view, he began taking multiple polaroids of a single space.
He realized that what resulted was a piece of art in itself, a patchwork narrative of the subject, another dimension to photography. He called the pieces the joiners.
In the early 60's while still in art-school Hockney had a rash of luck in meeting Andy Warhol and getting introduced to the entire pop-art crowd. He was able to sell some work and live for a year in America. But it was not New York that Hockney had set his sights on, California would be it.
