David Hockney has introduced a new and interesting direction to his practice. He has created a film, which is not something that he has undertaken much before.
Using modern technology, Hockney has used 9 cameras fixed to a frame structure, which is attached to his car. The cameras are placed at equal distances to form a 3x3 grid so that they can focus on the lower, midlle and foreground. He then drives down the 'tunnel' road during spring, sumer, autumn and winter.
The multiple cameras help to look more closely at certain aspect aspects of the view, whereas with one camera, you would have to be a lot further back to see entirety of the same view.
