F (Deutscher Film) exemplifies David Ostrowski's reductive approach to painting, where sparse gestures of acrylic and lacquer move across the canvas with an almost effortless, improvisational quality. A torn or placed fragment of paper interrupts the surface, introducing an element of collage that complicates the boundary between painting and assemblage. The artist's custom frame further asserts the work as a complete, self-contained object, reinforcing Ostrowski's interest in questioning the minimal conditions under which a painting can exist.
