These are expansible, often with accordion folds in the material. By extending the bellows and moving the lens, the photographer may focus on the film plane, and achieve close-up or macro focusing. Bellows also allow the photographer to correct perspectival aberrations by tilting or raising the lens.  ]]></note></mads>
