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.  ]]></termNote><termCreatedDate>2026-03-30 20:34:07</termCreatedDate><relation><relationType>BT</relationType><termId>31322938</termId><termName>camera components</termName><termType>PT</termType></relation><relation><relationType>RT</relationType><termId>31306461</termId><termName>lenses</termName><termType>PT</termType></relation></term>  </Zthes>
