Intro. to Color Management for Cultural Image Capture

Course Number: SC4A

Time: 16:30 – 18:30 (2 hours)
Track: Capture: Getting good color/data
Level: Introductory
Instructors: Don Williams and Peter Burns

Benefits: This course enables the attendee to:

  • Interpret and comply with customer imaging requirements.
  • Establish accountability for imaging performance problems.
  • Compare various levels of FADGI and Metamorfoze guidelines.
  • Critically evaluate manufacturers’ claims of resolution, color errors, and noise.

Course Description
This course provides an introduction to color management for cultural heritage image capture. We start with the elements of color vision that are behind all practical color imaging systems, then discuss how current imaging technologies for cameras and scanners are chosen to facilitate the capture of standard color images. Specifics of common image transformation from camera detector RGB signals to standard CIE colorimetry are explained. Color-difference measures based on CIELAB color space, and how ICC color profiles are used are explained. Specifically, the CIELAB-based color-difference method used in several institutional standards and guidelines (e.g., FADGI and Metamorfoze) is discussed using several examples.

This presentation is intended to complement another short course, SC1A:?Introduction to Color Measurement for Archiving.

Intended Audience: Managers, engineers, and technicians responsible for evaluating and monitoring scanner and camera performance, and emerging guidelines. This includes manufacturers, service providers, and content custodians. Some knowledge of digital scanner and camera operation technologies is assumed, but color science is not.

Don Williams is founder of Image Science Associates, a digital imaging consulting and software group. Their work focuses on quantitative performance metrics for digital capture of digital imaging devices, and imaging fidelity issues for the cultural heritage community. He has worked for a number of large cultural heritage institutes in practical implementation of image quality controls and is the prime architect for the GoldenThread image quality evaluation tools. He has taught short courses for many years and contributes to several imaging standards activities. 

Peter Burns is a consultant working in digital image evaluation, system monitoring, and image processing. He has experience in several areas of digital imaging, digital photography, mobile imaging, and cultural heritage.
