This volume presents the life work of the late Ruth Johnston-Feller, one of the nation's leading color scientists. It combines an overview of basic theoretical concepts with detailed, hands-on guidance for the professional conservator and conservation scientist. The author focuses on the application of color science to the solution of practical problems, providing a comprehensive discussion of the nondestructive spectrophotometric tools and techniques used to understand the color and appearance of materials during the technical examination of works of art. The book, which features numerous examples of reference reflectance spectra, can help prevent misinterpretation of color measurements and the erroneous conclusions that might result. Topics include spectrophotometry, colorimetry, colorant mixtures, analytical techniques, reflection, fluorescence, and the effects of extenders, fillers, and inerts.

“A curator, a paintings conservator, a photographer, and a conservation scientist walk into a bar.” What happens next? In lively and accessible prose, color science expert Roy S. Berns helps the reader understand complex color-technology concepts and offers solutions to problems that occur when art is displayed, conserved, imaged, or reproduced. Berns writes for two types of audiences: museum professionals seeking explanations for common color-related issues and students in conservation, museum studies, and art history programs. The seven chapters in the book fall naturally into two sections: fundamentals, covering topics such as spectral measurements, metamerism, and color inconstancy; and applications, where artwork display, painting materials, and color reproduction are discussed. A unique feature of this book is the use of more than 200 images as its main medium of communication, employing color physics, color vision, and imaging science to produce visualizations throughout the pages. An annotated bibliography complements the main text with suggestions for further reading and more in-depth study of particular topics. Engaging, incisive, and absolutely critical for any scholar or student interested in color science, Color Science and the Visual Arts is sure to become a key reference for the entire field.

Colour, Colour Measurement and Colour Change, the first new book in the expanded Science for Conservators series, explains the science of colour, colour measurement and colour change for conservators in a clear and comprehensible way, elucidating the topic for those with no scientific background. The book explains how and why we see colours and how colour and colour change can be measured, as well as clarifying why these would be done in a conservation context. It then examines the ways in which colour can change – such as darkening, yellowing, fading, blanching and patination – illustrating these in different types of cultural heritage materials, including metals, varnishes, plastics, textiles and paints. The final chapter explores how colour change can be reduced in different types of storage and display settings, and, in particular, what can be done to protect against damage by light, damp and pollutants. This book is an invaluable introduction to all aspects of the science of colour in conservation. It is suitable for students in undergraduate and postgraduate conservation programmes, as well as being a useful reference guide for practising conservators.

The role of exact sciences in connection with cultural heritage now is well established and a new scientific branch has been generated: Archaeometry. Literally, Archaeometry means measurement on ancient objects. It is a multidisciplinary field of investigations where the rigorous methods of exact sciences give a fundamental contribution to solving the problems associated with conservation and restoration, as well as to the study itself of the cultural heritage. Archaeometry, as a scientific research field, involves interdisciplinary groups formed by scholars of the humanistic area together with scientists: physicists, chemists, mathematicians, biologists, engineers, etc. The primary justification for the need of involving exact sciences in the field which, in the past, traditionally has been exclusive of Art Historians must no doubt be found in the conservation and restoration activities. The second argument which, in the public opinion, justifies the involvement of science with the world of Art is the confidence that scientific methods are infallible in unmasking forgeries. But in our opinion the awareness of the central role of scientific methods as a support for philological and historical investigations is still very little diffuse or, at least, finds it hard to become widespread. Perhaps also because of our mentality, Physics, compared to chemistry, is more apt to find applications in a context free from authentication or conservation implications.

In recent years more cultural institutions in hot and humid climates have been installing air-conditioning systems to protect their collections and provide comfort for both employees and visitors. This practice, however, can pose complications, including problems of installation and maintenance as well as structural damage to buildings, while failing to provide collections with a viable conservation environment. This volume offers hands-on guidance to the specific challenges involved in conserving cultural heritage in hot and humid climates. Initial chapters present scientific and geographic overviews of these climates, outline risk-based classifications for environmental control, and discuss related issues of human health and comfort. The authors then describe climate management strategies that offer effective and reliable alternatives to conventional air-conditioning systems and that require minimal intervention to the historic fabric of buildings that house collections. The book concludes with seven case studies of successful climate improvement projects undertaken by the Getty Conservation Institute in collaboration with cultural institutions around the world. Appendixes include a unit conversion table, a glossary, and a full bibliography. This book is an essential tool for cultural heritage conservators and museum curators, as well as other professionals involved in the design, construction, and maintenance of museums and other buildings housing cultural heritage collections in hot and humid climates. “It is absolutely right that conservation be in step with the socio-political context surrounding environmen­tally sound approaches. This text does that, and does it well. The authors have, admirably, been awarded the 2016 Prose Award for Environmental Science, and they are to be congratulated for producing a text that is seen as having an impact outside of the conservation sphere. The technical theory that underpins the text is accessible, and the solutions borne out through the case studies do present as being admirably pragmatic.”— Journal of the Institute of Conservation

In the fields of documentation and conservation of cultural heritage assets, there is a constant need for higher quality records and better analytical tools for extracting information about the condition of artefacts. Digital photography and digital image processing provide these capabilities, and recent technological advances in both fields promise new levels of performance for the capture and understanding of colour images. This inter-disciplinary book covers the imaging of decorated surfaces in historical buildings and the digitisation of documents, paintings and objects in museums and galleries, and shows how user requirements can be met by application of powerful digital imaging techniques. Numerous case studies illustrate the methods.

The main purpose of this book is to provide a modern review about recent advances in Fourier transforms as the most powerful analytical tool for high-tech application in electrical, electronic, and computer engineering, as well as Fourier transform spectral techniques with a wide range of biological, biomedical, biotechnological, pharmaceutical, and nanotechnological applications. The confluence of Fourier transform methods with high tech opens new opportunities for detection and handling of atoms and molecules using nanodevices, with potential for a large variety of scientific and technological applications.
