Axl Klein is a renowned German photographer specialising in advertising and people. He recently finished a major art project in which 55 celebrities were asked to display the emotion of anger.

Axl's idea was to create challenging images and also point out that anger is not necessarily a negative emotion but more a motivation for change. All participants, including Axl, gave their time for free and a selection of prints plus a book were put up for sale to raise funds for Amnesty International. The project came together under the title 'Zorn', the German word for rage.
