Channel 4 has been challenging teenagers to express their identity, what they want to say and how they want to be seen in the form of a self portrait. The most imaginative responses, ranging from digital imaging to video, music and writing, will be displayed at exhibition venues such as the National Portrait Gallery and on Channel 4. Self-portraits produced by celebrities supporting the campaign - including poet Benjamin Zephaniah, stand-up comedian Shazia Mirza and principal ballerina Darcey Bussell - will be broadcast on May 27 at 10.30am.
