When combined with software written at RIT, this system is capable of significantly higher color accuracy without a loss in spatial image quality. “CTM” stands for “color to match” the product name for a filter slider housing a pair of filters designed by the Roy Berns. Our particular camera is a new Sinar Photography AG system, consisting of a 86H 48MP color sensor, rePro camera body, eShutter with HR100 lens, and the CTM attachment. The first is easel based, using a high-resolution medium-format commercial camera and Xenon strobes, typically found in museum imaging services. Following rendering (synthesis), images are used for printing and web display. The archival images can be used directly by both conservators and conservation scientists. This approach will clarify the two imaging stages of analysis and synthesis. The purpose of the Studio is to lead by example and prove that an imaging studio using commercial equipment can provide both images for science and scholarly communication. Matlab was selected because we have over a decade of experience with this language and an extensive subroutine library of color-science tools. The specific software to be written is listed in the expected outcomes. A screenshot from ArtViewer is shown in Figure 13, a program that renders images for user-selectable lighting geometry. The software is executable and includes a graphical interface to run the software. As an example, all the four-light imaging software developed during the last Mellon-funded project is available for downloading. Funds from the proposed project will be used to maintain the commercial license during the course of the project. This enables executable software to be written and distributed, either as a commercial product or for free at our discretion. Any software developed during the proposed project will be downloadable for free from We are using the Matlab programming language and have purchased a commercial license during 2012 using Berns' discretionary funds. Such visits will be extremely valuable as a source of knowledge transfer for both imaging services and Berns.Īnother type of outreach is software. During the visit, a workshop and short course will be delivered. Each visit will last approximately one week. Roy Berns will visit three institutions per year, on average, and demonstrate the techniques developed and tested at the Studio. Workshops will be developed that are hands-on, in similar fashion to the workshop given during the previous Mellon-funded project, “Improving Artwork Reproduction Through 3D-Spectral Capture and Computer Graphics Rendering – Phase 2.” These will be presented both at RIT and museums. Such images and walk-through animations will be included in the short course notes. A virtual museum gallery was produced and the painting rendered for spot illumination, shown in the figure above. For example, a painting imaged with the four-light system was input to Maya, a computer-graphics rendering software package used by animators. It will also be a vehicle to demonstrate applications of spectral and four-light imaging systems. The will improve the general knowledge of museum personnel and provide important background that will aid in knowledge transfer of the results from the proposed project. There will be more emphasis on conservation than in the past, such as the American Institute of Conservation, the CIC Image Archiving conference, and the Museum Computer Network.Ī short course will be developed to teach color science to artists, conservators, and curators. We will continue to submit papers for conferences and refereed journals, in similar fashion to past projects. Outreach is a key component of the Studio, addressing the education barrier to incorporating scientific imaging within imaging services. The Studio is a natural extension of previous research sponsored by the Andrew W. The proposed Studio will contain aspects of both imaging services and conservation science departments found at museums, libraries, and archives. We firmly believe that the best way to effect lasting changes in how institutions digitize their cultural assets is to lead by example. The vision statement for the Studio is to promulgate scientific imaging practices within cultural heritage institutions.
