What struck me every time I looked at a David Hockney painting is the depth in them. This great perspective seeing and view line conscious eye of him, only matched by excellent wide-angle lenses we use in photography.
He paints like a wide-angle lens does when we photograph a sky with clouds or a landscape with a road. Well, that also means that we are little Hockneys as well, because one needs to see it first, the lens is only as good as the photographer that wields it. Yet Hockney’s paintings are wonderful to train your eye for perspectives and view lines. Look at them and your eye will learn. That’s enough, just look at them.
