The Art and Technique of Digital Color Correction
How to\" books are a dime a dozen. What makes this book special is that it is also a \"Why\" book. Hullfish sits down with world-class colorists and records not only what they do but why they do it. That's where the magic lies.
\"How\" is the question to ask if you want to become a craftsman. \"Why\" is the question that creates artists. I bought the first edition for \"How\" and came away with a lot of \"Why.\" This edition has lots more of both, with material from several additional world class colorists.
If you want an inside look into the art and craft of the professional colorist there's no better way to do it in book form. Whether you're learning to be a colorist or just want to understand what really happens when you decide something can be \"fixed in post,\" you need to read this book. -Art Adams, cinematographer/educator, ProVideoCoalition.com. This book just keeps getting better with each new edition. Steve Hullfish's approach is designed to teach techniques that transfer to a wide range of popular and accessible color correction tools. The intent is to demystify the process, so readers can learn the concepts and apply them, regardless of whether the software has sliders, wheels or curves. Best of all, Hullfish features extensive tips and tricks from some of the premier colorists in the country, so you can learn from the masters. If you only purchase one book on color correction, this is the essential guide to include in your library. -Oliver Peters, Oliver Peters Peters Post Production Services, LLC A terrific and much-needed book for anybody serious about digital color correction. Starting with the basics, it helps the reader work through a series of specific, well-illustrated examples, covering all the major software applications, and supports the text with insightful comments from prominent working colorists. All in all, it's essential reading for anyone who wants to improve their skills in this rapidly changing field. -Steve Cohen, editor, Emmy and ACE Eddie winner, author of Avid Agility.

Gabriel Lippmann's Colour Photography
Physicist Gabriel Lippmann's (1845–1921) photographic process is one of the oldest methods for producing colour photographs. So why do the achievements of this 1908 Nobel laureate remain mostly unknown outside niche circles? Using the centenary of Lippmann's death as an opportunity to reflect upon his scientific, photographic, and cultural legacy, this book is the first to explore his interferential colour photography. Initially disclosed in 1891, the emergence of this medium is considered here through three shaping forces: science, media, and museums.
A group of international scholars reassess Lippmann's reception in the history of science, where he is most recognised, by going well beyond his endeavours in France and delving into the complexity of his colour photography as a challenge to various historiographies. Moreover, they analyse colour photographs as optical media, thus pluralising Lippmann photography's ties to art, cultural and imperial history, as well as media archaeology. The contributors also focus on the interferential plate as a material object in need of both preservation and exhibition, one that continues to fascinate contemporary analogue photographers. This volume allows readers to get to know Lippmann, grasp the interdisciplinary complexity of his colourful work, and ultimately expand his place in the history of photography.

Color in Computer Vision
While the field of computer vision drives many of today's digital technologies and communication networks, the topic of color has emerged only recently in most computer vision applications. One of the most extensive works to date on color in computer vision, this book provides a complete set of tools for working with color in the field of image understanding.Based on the authors' intense collaboration for more than a decade and drawing on the latest thinking in the field of computer science, the book integrates topics from color science and computer vision, clearly linking theories, techniques, machine learning, and applications. The fundamental basics, sample applications, and downloadable versions of the software and data sets are also included. Clear, thorough, and practical, Color in Computer Vision explains:Computer vision, including color-driven algorithms and quantitative results of various state-of-the-art methodsColor science topics such as color systems, color reflection mechanisms, color invariance, and color constancyDigital image processing, including edge detection, feature extraction, image segmentation, and image transformationsSignal processing techniques for the development of both image processing and machine learningRobotics and artificial intelligence, including such topics as supervised learning and classifiers for object and scene categorization Researchers and professionals in computer science, computer vision, color science, electrical engineering, and signal processing will learn how to implement color in computer vision applications and gain insight into future developments in this dynamic and expanding field.

The Importance of Close Follow-Up in Patients with Early-Grade Diabetic Retinopathy: A Taiwan Population-Based Study Grading via Deep Learning Model
(1) Background: Diabetic retinopathy (DR) can cause blindness. Current guidelines on diabetic eye care recommend more frequent eye examinations for more severe DR to prevent deterioration. However, close follow-up and early intervention at earlier stages are important for the prevention of disease progression of other diabetes mellitus (DM) complications. The study was designed to investigate the association between different stages of DR in type 2 DM patients and the progression of DR; (2) Methods: A total of 2623 type 2 DM patients were included in this study. In these patients, a total of 14,409 fundus color photographs was obtained. The primary outcome was the progression of DR; (3) Results: The progression of DR was highly associated with the initial grade of DR (p < 0.001). Severe nonproliferative diabetic retinopathy (NPDR) was the most likely to progress to proliferative diabetic retinopathy (PDR), followed by moderate NPDR, mild NPDR, and no retinopathy. However, progression to the next stage of DR showed a different trend. We used no retinopathy as a reference. Mild NPDR showed the highest risk for progression to the next stage [hazard ratio (HR): 2.00 (95% conference interval (CI): 1.72–2.32)] relative to higher initial grades [HR (moderate NPDR): 1.82 (95% CI: 1.58–2.09) and HR (severe NPDR): 0.87 (95% CI: 0.69–1.09)]. The same trend was observed in the multivariate analysis, in which mild NPDR presented the highest risk for progression to the next stage (adjusted HR (mild NPDR): 1.95 (95% CI: 1.68–2.27), adjusted HR (moderate NPDR): 1.73 (95% CI: 1.50–1.99), and adjusted HR (severe NPDR): 0.82 (95% CI: 0.65–1.03)); (4) Conclusions: Type 2 diabetic patients with earlier-grade DR appeared to exhibit more rapid development to the next grade in our study. As these findings show, more frequent fundus color photography follow-up in earlier-grade DR patients is important to slow DR progression and awaken self-perception.

Colour Reproduction in Electronic Imaging Systems
With the move of cinema away from film, the adoption of electronic-based production throughout all media is now complete. In order to exploit its advantages, the accurate definition, measurement and reproduction of colour has become more important than ever to achieve the best fidelity of colour reproduction. This book is concerned with providing readers with all they need to know about colour: how it is perceived and described, how it is measured and generated and how it is reproduced in colour systems. It serves as both a tutorial and a reference book, defining what we mean by colour and providing an explanation of the proper derivation of chromaticity charts and through to the means of ensuring accurate colour management. Key Features: * Addresses important theory and common misconceptions in colour science and reproduction, from the perception and characteristics of colour to the practicalities of its rendering in the fields of television, photography and cinematography * Offers a clear treatment of the CIE chromaticity charts and their related calculations, supporting discussion on system primaries, their colour gamuts and the derivation of their contingent red, green and blue camera spectral sensitivities * Reviews the next state-of-the-art developments in colour reproduction beyond current solutions, from Ultra-High Definition Television for the 2020s to laser projectors with unprecedented colour range for the digital cinema * Includes a companion website hosting a workbook consisting of invaluable macro-enabled data worksheets; JPEG files containing images referred to in the book, including colour bars and grey scale charts to establish perceived contrast range under different environmental conditions; and, guides to both the workbook and JPEG files
