I remember visiting an exhibition a couple of years ago at the Tate Modern called 'Street and Studio' which looked at photography taken on the streets or in the photographer's studio. The exhibition showed the contrasts between the studio, where everything is planned and positioned, and on the street, where there is movement and unpredictable things going on all the time.

Banksy is also another artist who uses the ideas of 'exposure'

 I think Banksy's work is clever because it's effectively 'mocking' and exploiting what is seen as 'PC' in our country. Especially because his work is done in secret, yet the results are so prominent and public. 

 The above piece of work by Banksy is interesting because it exploits the idea that we're all guilty until proven innocent, even children.
