With this week's freezing temperatures it's best to stay indoors. Take a trip to the warmBrooklyn Museum to see the current exhibition Norman Rockwell: Behind the Camera (On until April 10, 2011). The exhibition shows Norman Rockwell's creative process by displaying many of the photographs he took as part of his work. By using photographs as references, Rockwell was able to capture small details and intricate plays of light. He would stage the entire composition in one photograph or collage many different elements from different photographs to create a cohesive composition. The exhibition displays the photographs along with Rockwell's paintings, drawings, and tear sheets.
