Mastering Light: Reproduction, Reality, and Augmentation
Michael J. Murdoch
head, Integrated Sciences Academy, and associate professor, Munsell Color Science Laboratory, Rochester Institute of Technology
As we gather in the City of Light, consider that everything visible is light. We, color and imaging scientists and practitioners, are masters of light, reproducing light through imaging, creating and utilizing light in our real environment, and augmenting our illuminated reality with advanced displays and optics. Imaging, a core topic of CIC, is about the reproduction of light, which is foremost a question of tone and color reproduction, and we develop and master technologies from reflective pigments to emissive displays. Reality itself is rendered and sensed with light, and as we choose to light our environment with LED illumination, color rendition is a central question for visual quality. Reality and imaging converge in augmented reality—AR—which can insert interactive imagery into our illuminated world. In AR, this mix of real and augmented reveals important questions about adaptation and color perception. Mastering light in real and augmented reality incorporates the newest, evolving technologies, while we rely on the foundations of our predecessors: both the intuitive artists whose paintings we still admire, and the rational scientists whose findings we still trust.

On Evaluating Skin Color User Preferences for Smartphone Photography
Sira Ferradans
AI scientific director, DXOMARK
Portraits are the most common use case for smartphone photography, however, producing a realistic and pleasant skin tone in real scenarios is still challenging for all. Around 20% of portraits are discarded due to bad image quality, and a photographer’s edition (raw capture with a professional photographer retouch) is mostly preferred to a smartphone’s, which suggests that contemporary smartphone cameras are far from solving the skin tone rendition problem.
These challenges are due to a lack of a clear user preferences target definition regarding color skin tone rendering. In literature, we find mostly studies that evaluate synthetic modifications of laboratory portraits. This talk shows that real setups are more complex to evaluate, and user preferences depend on many factors.
Producing non-homogeneous quality rendition across skin tones has become a sensitive issue, making its evaluation crucial. This talk discusses the challenges of systematically evaluating diverse skin tones in the lab using realistic mannequins, and how defining a target can pave the way to automatizing skin tone rendition evaluation with machine learning.

Colour Science vs. Colour Engineering in High-End Motion Picture
Daniele Siragusano
image engineer, FilmLight
Professional VFX and Finishing Applications rarely use cutting-edge colour science research results.
It seems that every software vendor reinvents the wheel of colour management over and over again.
Even open-source initiatives like the Academy Colour Encoding System (ACES) utilise little of the findings produced by academia in recent years.
Almost every blockbuster movie is produced within a unique colour management environment created by a specialised "Inhouse Colour Scientist" in Post Facilities. Every camera manufacturer ships with its proprietary "Colour Science". Every Colour Grading Software has custom colour models for every step in the process.
Why is this so?
It seems that the requirements for high-end motion picture workflows are very special and not well-established in the academic environment.
This keynote formalizes some of the most critical requirements for image algorithms in motion pictures, hoping to better align Colour Science and Colour Engineering for the big screen.
