NEW Camera Color Profiles: The Theory, Practice, and Pitfalls
Instructor(s): David R Wyble, Gray Sky Imaging Inc., and Doug Peterson, Digital Transitions
Level: Intermediate
Duration: 4 hours
Prerequisites: General familiarity with digitization using a camera-based system
Course Time: 8:45-13:00
 
Benefits
This course enables the attendee to:
 - Understand the basic science of color and measurements as it is applied to digital imaging. 
 - Understand why cameras need to be profiled to deliver accurate color.
 - Understand how to profile a camera for reflective materials like paintings. 
 - Understand how to profile a camera for transmissive materials like photographic film.
 - Understand how to avoid false-confidence in your color accuracy.
 - Understand how DualRGB can be used to further improve color accuracy.
 
Course Description
Hopefully you already profile your camera, but even if you do, how much do you understand the science and practice of the profiling process? In this class Dave Wyble and Doug Peterson will team up to holistically cover the topic of camera profiling for both reflective and transmissive materials. Holistic digital imaging? Yes, because we will discuss the relationship between the targets you choose, the camera, lighting, and processing you use, and the results you’ll get for various subject matter. You’ll learn what color really is, why cameras need help reproducing it accurately, and how to create profiles that perform well holistically rather than focusing on getting the lowest possible deltaE shown in whatever profiling software.
 
Intended Audience: This class is intended for current or future practitioners of heritage digitization and those that supervise them.
 
David R. Wyble is president and co-founder of Gray Sky Imaging, Inc., and president of Avian Rochester, LLC. Founded in 2022, Gray Sky Imaging provides consulting and product development to improve the imaging capabilities of the library, archiving, and museum fields.
