If you get very close to an old painting (like Cameron in “Ferris Bueller’s Day Off”), you are sure to notice that the paint has cracked to a certain degree. This damage is caused by natural light that any painting on display is exposed to. This raises the question: Can we continue displaying priceless works of art if we know that displaying them is damaging them? Is there any other way to save them?

Tess discusses these questions with Dr Alp Durmus, honorary associate of the University of Sydney School for Architecture, Design and Planning.
