Wolterink shoots each individual cupboard, drawer, built-in appliance—even the borders of the image. Sometimes the doors can be easily opened; other times they are removed. He then takes each frame and combines them into one image, so details of the items in the kitchen remain sharp. “My work is a combination of documentary and collage,” Wolterink said. “I usually visit each kitchen twice,” Wolterink explained about the documentary aspect of the project. “I ask them not to clean. The first time I visit is to meet them and talk about the project. When I come back the second time, I know what the kitchen looks like, and I know if they have moved things around or if they have cleaned it!” (via Erik Klein Wolterink: Kitchen Portraits examines the multicultural reality of kitchens (PHOTOS).)
