A new satellite workshop for Progress in Colour Studies – PICS 2016:
„Archiving Cultural Heritage Using Multi-Spectral and Multi-Light Photography“ led by Roy Berns.
The course shall be delivered on the Monday afternoon and Tuesday (full day) preceding PICS (12th/13th September 2016) at the National Gallery in London.
The course details are as follows:
Today’s medium-format cameras and lighting have the capabilities to extend an imaging studio’s services beyond delivering a single RGB image. This is achieved using cameras that record more than RGB, that is, multi-spectral cameras, using lights in different locations and recording sequential images, and physically based rendering. This 1½-day workshop will teach photographers the principles and applications of color science, multi-spectral imaging, and multi-light imaging. The course is divided into six two-hour modules:
Module 1: Color Science and the Visual Arts – Principles
Spectral measurements, color vision, spatial vision, exploiting our color and spatial vision to create and conserve artwork.
Module 2: Color Science and the Visual Arts – Applications
Numerical color descriptions: colorimetry, CIELAB, and “∆E”, principles of color reproduction, overview of ICC color management.
Module 3: Multi-Spectral Imaging – Principles
Colorimetric imaging, color camera and two colored filters (Dual-RGB) colorimetric and multi-spectral imaging, monochrome camera and filter wheel multi-spectral imaging.
Module 4: Multi-Spectral Imaging – Hands-On
Placing lighting and camera, calibrating for colorimetric and multi-spectral imaging, imaging representative artwork, processing using software written by the Studio for Scientific Imaging.
Module 5: Multi-Light Photography – Principles
Diffuse, macroscopic, and microscopic properties of colored surfaces, surface normal to define macroscopic properties, measuring surface normal using multiple light geometries, combining diffuse color and surface normal to render objects.
Module 6: Multi-Light Photography – Hands-On
Multiple-light placement, calibrating light position, calibrating for colorimetric and multi-spectral imaging, imaging representative artwork, processing using software written by the Studio for Scientific Imaging, processing using computer-graphics software.
Modules 1 and 2 shall be delivered on the Monday afternoon, and modules 3-6 shall follow on Tuesday. Spaces are limited to 50 on the Monday, and 20 on the Tuesday (as the Tuesday modules require use of the photographic studio).

About the Instructor: Dr. Roy S. 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 where he developed both M.S. and Ph.D. degree programs in Color Science. 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. Berns’ main research focus is using color and imaging sciences for the visual arts, particularly paintings, including: 3-D imaging and computer-graphics rendering; spectral-based imaging, archiving, and reproduction; pigment mapping; and digital reconstructions of faded and darkened artwork. Berns was part of the team that produced the color visualization of the Art Institute of Chicago’s Bedroom by Vincent van Gogh: https://www.youtube.com/watch?v=9SsUzaIDsHo.
The workshop is free to attend, due to the generosity of the National Gallery in providing the space, and of the instructor (and his funders) in providing time and expertise.
