Written in language understandable for the non-technical reader, the book begins with a brief history of so-called science-based conservation, which is based on chemistry, physics and engineering, and examines how it influences conservation ethics and conservation decisions. It considers the concepts of originality and original appearance, and how people see and perceive objects, looking in particular at the results of the relatively new technology of eye-tracking. Wei then moves on to critically examine advanced technologies such as colour modelling, hyperspectral imaging, texture mapping, virtual retouching and digital reproductions and considers what they offer for determining original appearance of artworks and other cultural heritage objects. The book concludes with some reflections on the future of conservation and science-based conservation, calling for more thoughtful consideration of what it is that conservation scientists are offering, and why and for whom it is being offered.
