“[by] merely suggesting rather than sharply delineating objects, emphasising ambiguity and openness, employing serial methods, and including the viewer in art [a painting] becomes an incarnation of the creative process.”
— Art historian Karin Sagner-Dychting writing about Monet’s late paintings, Monet and Modernism, page 29
Or put another way: look harder and don’t put in so much meticulous detail. Don’t tell everything in a painting, leave parts open to interpretation for people to determine their own story from it. Don’t have detail across the whole painting down to the single brush hair level, but let what looks real from a little distance dissolve into pieces of colour as you look closely. It’s far more interesting.
