Hockney's 'Joiner' artist research

In the early 1980's, Hockney began to produce photo collages, which he called "joiners".

This is probably a closer description of how we see the world - from multiple viewpoints that are then pieced together by our mind. In this joiner by David Hockney he has tried to create this effect out of 24 Polaroid prints. He did this because he was interested in how we see and depict space and time. His is interested in how we turn a 3 dimensional world into a 2 dimensional image, how perspective is used in western art and how space is treated differently in non-western art. He did not particularly make joiners because he liked the novel effect of using photographs in this way. However, he did like the way this technique allowed the viewer to read space. He sometimes laid the images out in a neat grid.
