As laboratory manager, he supervised and was directly involved in the following areas: visual and computer-assisted instrumental color matching, product development, and material quality assurance for continuous dyed and printed carpets. In fall 1980, he received a research assistantship to attend Rensselaer Polytechnic Institute to study color science under the direction of Dr. Fred Billmeyer, Jr. While at Rensselaer, Dr. Berns received a Kollmorgen Foundation Grant to develop computer algorithms to be used in improving the color constancy of the Munsell Book of Color. He received his doctorate degree after studying with Dr. Billmeyer for three and one half years. In 1984, Dr. Berns joined the Munsell Color Science Laboratory as an Assistant Professor in Photographic Science at the Rochester Institute of Technology. Along with Dr. Franc Grum, Director of the Munsell Color Science Laboratory, he developed research, measurement, and academic programs in color science. His primary responsibilities included academic curricula, industrial short courses and seminars, and research in color science, appearance, and technology. In May, 1987, Dr. Berns was named the Richard S. Hunter Professor in Color Science, Appearance and Technology. Implicit in this distinguished professorship is the responsibility to assume a leadership role in color related activities on the RIT campus and to initiate research specifically in the interaction of geometric properties of materials and color appearance and generally in applied colorimetry. Since assuming the professorship, Dr. Berns has raised several million dollars in endowed scholarships, fellowships, equipment donations, and unrestricted grants for research and education in color science. In 1990, Dr. Berns was awarded the Inter-Society Color
Council Macbeth Award. This award is presented biannually for recent
significant contributions to the field of color. During the early 1990's, Dr. Berns derived the CIE94
color difference equation based on his and other experimental data,
summarized in CIE Publication 116. He also contributed to CIE Publication 101
describing the influence of parametric factors on color discrimination. As chair, he wrote the current CIE recommendation
(CIE Publication 122) on building colorimetric device profiles for
computer-controlled CRT displays based largely on his and his student’s
research. Currently, Dr. Berns' primary research interest is the
spectral archiving and reproduction of cultural heritage. This includes
visible multi-channel image acquisition, data-efficient spectral
encoding, and multi-ink ink-jet printing. He is also interested
in practical color management, digital photography, and color tolerance
equations. In CIE technical committee 1-47 (hue and lightness-dependent
correction to industrial color-difference evaluation), Dr. Berns
has derived the hue-angle dependent function for the new CIEDE2000
color-difference equation (see reference 111). At RIT, Dr. Berns teaches courses in applied colorimetry
and the color modeling of materials and imaging systems. The Center for Imaging Science accepts visiting scientists supported
by their companies to study and perform research with individual
faculty members. Scientists
from Konica, Fuji, Fujitsu, Fuji-Xerox, Dupont, Panasonic, Samsung
Aerospace, Samsung SAIT, Toppan, and Sony have engaged in research
under Dr. Berns’ guidance. Through development efforts with personal
and corporate donors, the Grum Memorial Scholarship, the Macbeth-Engel
Fellowship in Color Science, and the Saltzman Memorial Fund
were promulgated at RIT under Dr. Berns’ leadership.
During the 1999 academic year, Dr. Berns was a Visiting Senior Fellow in Conservation Science at the National Gallery of Art, Washington. He was involved in four research topics: colorant selection for inpainting, direct digital capture of paintings, metamerism basics for artists, and quantifying the optical properties of painting varnishes using image analysis. Also during 1999, Dr. Berns was awarded two technical
awards: The Society of Imaging Science and Technology awarded Dr.
Koichi Iino and Dr. Berns the Journal Award for the best imaging
science paper during 1998 (see references 77 and 78); the Society
of Plastics Engineers Color and Appearance Division awarded Dr.
Berns with the best paper of the 1999 ANTEC conference (see reference 93). During 2000, Dr. Berns was invited to participate in
the Technical Advisory Group of the Star-Spangled Banner Preservation
Project. Also during 2000, he wrote the third edition of Billmeyer
and Saltzman's Principles of Color Technology. In 2002, Dr. Berns
was made a fellow of the Society of Imaging Science and Technology.
He is currently involved in a joint research program in museum imaging
with the National Gallery of Art, Washington, DC and the Museum
of Modern Art, New York. Dr. Berns has presented invited papers and lectures at
the following organizations: International Commission on Illumination,
International Association of Colour, Inter-Society Color Council,
Royal Photographic Society, Society of Imaging Science and Technology,
Society for Information Display, International Society for Optical
Engineering, Optical Society of America, Society of Multispectral
Imaging of Japan, Detroit Color Council, American Association of
Textile Chemists and Colorists, Society of Plastics Engineers, and
the Australian Color Society. He
has lectured in countries including Canada, England, France, Monaco,
Germany, Italy, Hungary, Netherlands, Sweden, Japan, Argentina,
and Australia. TEXTBOOKS AND BOOK CHAPTERS R. S. Berns, Billmeyer and Saltzman Principles of Color Technology, 3rd ed., John Wiley & Sons, New York, 2000.
