Roy Berns is the Richard S. Hunter Professor in Color Science, Appearance, and Technology within the Program of Color Science at Rochester Institute of Technology, USA. He directs the Andrew W. Mellon Studio for Scientific Imaging and Archiving of Cultural Heritage. He received B.S. and M.S. degrees in Textiles from the University of California at Davis and a Ph.D. degree in Chemistry from Rensselaer Polytechnic Institute. He has received lifetime achievement awards from the International Association of Colour, the Inter-Society Color Council, the Colour Group of Great Britain, and the Society of Imaging Science and Technology. The subject of Berns’ doctoral dissertation was designing a Munsell Book of Color where its appearance was invariant to changes in lighting. He is the author of Color Science and the Visual Arts: A Guide for Conservators, Curators and the Curious. He is excited to return to the Munsell system.

Development of the Munsell Color Order System
Imagine the difficulties of communicating a color change without precise definitions or physical examples. As a textile colorist, I was stymied translating a variety of adjectives to dye amounts. Albert H. Munsell, a professor at Massachusetts Normal Art School (now Massachusetts College of Art and Design) was faced with a similar challenge. His solution was to invent a new way to organize colors and an accompanying color atlas. The key invention was Chroma, a measure of chromatic intensity at constant hue and lightness. This new dimension of color was remarkable since mixtures of artist materials such as a tint series do not maintain constant lightness. Munsell had to divorce himself from producing color and consider color conceptually. This presentation will explore how Professor Munsell came to develop his new system, its properties, and its evolution during the 20th Century.
Tuesday, June 12 - PM Breakout Session Tutorial
Archive Your Own Artwork Photographically
Many of today’s digital cameras have sufficient quality for use in artwork documentation. This tutorial will first review quality criteria including resolution, color accuracy, color encoding, bit depth, image noise, and sharpness. We will next consider how to photograph artwork that is repeatable and scientific. This includes adding reference targets into the frame. We will conclude with a demonstration of an easy-to-use color management system. Participants should have general knowledge about using a single lens reflex camera.
