Bringing back to Andy, photography is important in his work as his works are biodegradable. Because of this, it is of utmost importance to document his works, to prove that his works existed, before they decay and return to nature. Photographs last for a long time, thus, Andy uses photography in his work. Also, if he should document his works by painting pictures, then they would seem unrealistic as his works tend to be abstract-looking and do not ‘fit’ in with nature. Thus, photography gives a touch of realness in his works; the photos of artworks taken are more for the sake of recording evidence rather than for the purpose of art.
