1. Thomas Demand

At 303 through December 22

After a research visit, Demand meticulously reconstructed and photographed the Nigerian embassy in Rome. In his studio.

2. Thomas Ruff

At David Zwirner through December 22

Best-known for aestheticizing Internet porn (blurred and enlarged, it looks anything but racy), Ruff gives wartime imagery a similar treatment.

3. Wolfgang Tillmans

At Andrea Rosen through November 24

Take some time with this one: Tillmans uses photographs to create a cerebral in-gallery experience, this time inspired by impulse and boundaries.
