Illumination, Color and Imaging


Book Description

This much needed, comprehensive and modern reference on display technology, illumination sources and color imaging focuses on visual effects and how reproduced images are best matched to human visual features. As such, it teaches readers how to exploit the knowledge of human color information processing to design usable, ergonomic, and pleasing displays or visual environments. The contents describe design principles and methods to optimize self-luminous visual technologies for the human user, including modern still and motion image displays, and indoor light sources. Design principles and methods are derived from the knowledge of the human visual system, with a special emphasis on color vision, color cognition, color harmony, color preference and visually evoked emotions. The expert authors include the most important and latest applications of the design principles and methods, forming a comprehensive view of human color information processing from the receptors through the retina via high-level visual perception right up to the level of cognition, preference, harmony, as well as visually evoked emotions. This book is included in the Wiley SID Series.

Illumination and Color in Computer Generated Imagery


Book Description

In a very broad sense the historical development of computer graphics can be considered in three phases, each a giant step down the road towards "realistic" computer generated images. The first, during the late 1960's and early 1970's, can perhaps be characterized as the "wire frame" era. Basically pictures were composed of lines. Considerable em phasis was placed on "real time" interactive manipulation of the model. As models became more complex and as raster technology developed, eliminating the hidden lines or hidden surfaces from the image became critical for visual understanding. This requirement resulted in the second phase of computer graphics, the "hidden surface" era, that developed during the 1970's and early 1980's. The names associated with hidden surface algorithms read like a who's who of computer graphics. The cul mination of the hidden surface era and the beginning of the current and third era in computer graphics, the "rendering" era, was Turner Whitted's incorporation of a global illumination model into the ray trac ing algorithm. Now the goal was not just to generate an image, but to generate a realistic appearing image.




Color and Light


Book Description

Unlike many other art books only give recipes for mixing colors or describe step-by-step painting techniques, *Color and Light* answers the questions that realist painters continually ask, such as: "What happens with sky colors at sunset?", "How do colors change with distance?", and "What makes a form look three-dimensional?" Author James Gurney draws on his experience as a plain-air painter and science illustrator to share a wealth of information about the realist painter's most fundamental tools: color and light. He bridges the gap between abstract theory and practical knowledge for traditional and digital artists of all levels of experience.




Color Imaging


Book Description

This book provides the reader with an understanding of what color is, where color comes from, and how color can be used correctly in many different applications. The authors first treat the physics of light and its interaction with matter at the atomic level, so that the origins of color can be appreciated. The intimate relationship between energy levels, orbital states, and electromagnetic waves helps to explain why diamonds shimmer, rubies are red, and the feathers of the Blue Jay are blue. Then, color theory is explained from its origin to the current state of the art, including image capture and display as well as the practical use of color in disciplines such as computer graphics, computer vision, photography, and film.







Daylight Illumination–Color–Contrast Tables for Full-form Objects


Book Description

Daylight Illumination-Color-Contrast Tables for Full-form Objects is the result of a major computational project concerning the illumination, color, and contrast conditions in naturally illuminated objects. The project from which this two-chapter book is derived is originally conceived in support of the various remote sensing and image processing activities of the Deutsche Forschungs- und Versuchsanstalt für Luft- und Raumfahrt, Oberpfaffenhofen, West Germany DFVLR, in particular, those depending on the quantitative photometric and colorimetric evaluation of photographs and other environmental records. This book contains a comprehensive set of tables, from which often-needed reference and engineering data can be taken on the inherent illumination, color, and contrast in a generalized full-form model object illuminated by the sun, the sky, and light reflected from the ground, and viewed by a nearby observer. The computations leading to the tables pertaining to the luminance and color distributions in the sky were carried out at the Meteorologisches Institut der Universität München.




Introduction to Color Imaging Science


Book Description

Colour imaging technology has become almost ubiquitous in modern life in the form of monitors, liquid crystal screens, colour printers, scanners, and digital cameras. This book is a comprehensive guide to the scientific and engineering principles of colour imaging. It covers the physics of light and colour, how the eye and physical devices capture colour images, how colour is measured and calibrated, and how images are processed. It stresses physical principles and includes a wealth of real-world examples. The book will be of value to scientists and engineers in the colour imaging industry and, with homework problems, can also be used as a text for graduate courses on colour imaging.




Chroma


Book Description

Learning to work with light is an important milestone in every photographer’s career, and the ability to craft light to fit your vision for an image is a skill that cannot be overrated. Most often, that crafting of light is spoken of in terms of the quality and quantity of light. But there is an important, third component of light that heavily influences the final look of the image: the color of light. In Chroma: A Photographer’s Guide to Lighting with Color, photographer Nick Fancher helps you elevate your game when it comes to introducing the bold, creative, and intentional use of color into your work.

Whether you’re using a high-powered strobe or a small hotshoe flash, Chroma is for you. Nick begins with a discussion of color theory, gels, and white balance, then examines how to determine which colors complement your subject matter (whether that’s people or products). He moves on to cover topics such as:

  • Balancing, mixing, and overpowering ambient light with artificial light
  • Layering colors for unique color combinations
  • Mixing hard and soft light to achieve extremely rich color
  • Lighting detail and texture
  • Modifier options, such as ring flash, snoots, barn doors, softboxes, and filters
  • Gobos to control the light
  • Post-processing for vibrant, powerful colors
  • How (and why) to light with color, even when the end goal is a black and white image

Illustrated throughout with innovative and expressive imagery, Chroma also includes behind-the-scenes photos, lighting diagrams, and Lightroom settings so you can follow along from the initial concept through to the final edit.
