How do you make a documentary about abstract painting? When your subject strives for the indescribable, the normal tools of narration and interview become glaringly imperfect; I sympathize with any journalist who feels a sense of futility in the face of a work of art whose emotive power might be ineffable. This includes Corinna Belz, whose film “Gerhard Richter Painting” relies very little on interviews and stated history, and very heavily on long shots of the artist painting in his studio.
