Los Angeles artist Paul Sietsema presents an exceptional body of recent drawings and films in SFMOMA's New Work series. Sietsema straddles several media within a single piece: once his renderings of plant life, aristocratic chambers, and stone-age relics are meticulously crafted into models, the artist then films the fruits of his labor. But Sietsema doesn't simply transcribe a concept from one medium to the next. He works like a translator, keenly aware of the way his audience's understanding of the material changes with each piece's format.
