This workshop will provide participants with practical experience on three iterations of the microfading tester (MFT) instrument commonly in use today: the original Whitmore MFT design, the Retroreflective MFT, and the Fotonowy MFT. The audience for this workshop includes prospective and emerging MFT users, as well as those interested in alternatives to their current MFT setups.
Introduced in the mid-1990s by conservation scientist Paul Whitmore (Whitmore, Pan, and Bailie, JAIC 1999), the MFT has become an important preventive conservation tool for assessing the light sensitivity of an object. By exposing an object to an intense and tiny spot of light—greater than 1 million lux and less than 0.5 mm in diameter—and simultaneously monitoring color change with a spectrometer, the MFT provides information on an object’s vulnerability to light, as well as supporting object selection for exhibitions and the development of object-specific lighting guidelines for display.
Though the MFT is employed at heritage institutions around the world, there have been obstacles to its more widespread use. Because it is a unique technique that emerged from within the conservation field rather than from a commercial manufacturer, the formal training and technical support normally offered by instrument companies have not been available. Over the years, MFT users also began exploring alternatives to the original Whitmore MFT setup, including changes to the light source, measurement geometry, and means of automation. Thus, it is incumbent on the conservation field itself to support MFT practice, and this training workshop represents a contribution to this effort.
The bulk of the workshop will be dedicated to gaining hands-on experience with the Whitmore MFT, Retroreflective MFT, and Fotonowy MFT. During three 90-minute sessions on each instrument, participants will work in small groups with expert instructors to begin learning how to operate the instrument (choosing test locations, assessing the light source, establishing test parameters, focusing the light spot, conducting the tests) and communicate the results (analyzing and interpreting the data, preparing reports, impacting lighting guidelines). Information will also be shared on the acquisition, assembly, portability, and maintenance of each instrument. The workshop will include group discussion of general MFT concepts and case studies, and a Q&A.
This workshop is organized by AIC’s Microfading Tester International Discussion Group (MFT-IDG) in collaboration with the Academy Museum of Motion Pictures, Canadian Conservation Institute, Canadian Museum of History, Field Museum, Getty Conservation Institute, Ingenium, Library of Congress, Musée des Beaux-arts de Montréal, Museum of Modern Art, and National Galleries of Scotland.
The workshop will take place at Musée des beaux-arts de Montréal,1380 Sherbrooke Street W, Montreal. Meet at the conference center at 8:15am for complimentary transportation.

JP Brown is the Senior Conservator at the Field Museum, Chicago, IL where he has worked for the last 20 years. He is the author of the current iteration of the free SpectralViewer MFT software. Prior to joining the Field he designed and built real-time computer-based environmental monitoring systems for historic buildings, taught practical and preventive conservation at University College Cardiff, and worked as an archaeological conservator at the Yorkshire and Humberside Museums Council. He holds degrees in Archaeological Conservation (University College Cardiff, 1986), and Computer Science (University of Chicago, 2005) and currently specializes in objects conservation, real-time environmental monitoring and control, software solutions to conservation problems, and the 3D imaging of artifacts.
Cindy Connelly Ryan is a preservation science specialist in the Library of Congress Preservation Research and Testing Division, with a dual background in physics(Carnegie-Mellon University) and art conservation (New York University). Her current projects focus on developing instrumentation and best practices for identification of dyes and pigments, XRF, and MFT; reconstruction of obsolete historic artists’ materials; and conducting analytical studies of collection items. She frequently collaborates with Conservation colleagues on assessing conservation techniques, particularly for iron gall ink and verdigris. Cindy is the programming officer of the MFT-IDG, and has been an MFT practitioner since 2007, using the Whitmore, Fotonowy, and Thomas designs.
Kirsten Dunne ACR is Senior Projects Conservator at the National Galleries of Scotland, where she has worked since 2005. She trained in Paper Conservation but since 2019 her role has focused on Time Based Media, Microfading and the application of technology to conservation practice, including conservation created data and documentation. She was trained by Bruce Ford and has used a Whitmore model Microfader since 2012, applying it to risk-based collections management for the NGS collection. Kirsten sits on the committee of the American Institute of Conservation International Microfading Discussion group, acting as Information Repository Officer. She holds an MA in Conservation of Fine Art, Works of Art on Paper from Northumbria University and an MA in History of Art from Edinburgh University.
