In this fascinating book Stephen Dalton takes the reader on a journey, recounting how he started in photography and how he became fascinated with the idea of photographing insects and birds in flight. When Dalton started to combine his interests in nature and photography, no photographer had succeeded in capturing on film a focused image of an animal in midair. There were no digital cameras, no high-speed film, only primitive flash units powered by a heavy car battery. Color film took a week or more to be sent away and processed, too late for Dalton to make adjustments to his camera and flash set-up. There were also no publications to learn from. Dalton describes how persistence, hard work and sheer faith that it could be done pushed him to experiment with a variety of methods. Two years of repeated attempts, an understanding of flight mechanics and insight into the art of photography brought success: he captured a sharply focused image of a barn owl leaving its nest. Dalton had created the art of motion photography. Capturing Motion: My Life in High Speed Nature Photography is part memoir, part adventure story and part scientific explanation, illustrated throughout with Dalton's pioneering photographs. Dalton explains how the photographic equipment of the time worked and takes the reader on his journeys into the English countryside in the 1960s as he searched for subjects. Each attempt could be long and frustrating but success finally came with his image of a barn owl in flight: We employed two cameras set-up side by side in the hide, one containing color film that had to be sent away to Kodak for processing, which took a week, while the other was loaded with black and white film. When the owl took off both cameras recorded two almost identical images. More often than not the negatives revealed that at least one of the flash heads failed to fire, ruining the chance of obtaining the lighting so carefully planned. Even when we managed to obtain an image, the chances were that the wings were not in an attractive position. By now, after three weeks our patience was running thin. Although we had managed to obtain a few indifferent pictures, none of them did justice to the bird and the setting. I decided to struggle on for a few more days. A couple of evenings had passed when out of the blue everything jelled - next morning from out of the developing tank I withdrew a strip of dripping negatives that held the image that had been in my mind's eye for weeks - all four flash lamps had fired and the owl's wings were perfect. Capturing Motion follows the incredible journey of a highly skilled and creative nature photographer inventing an entirely new method. All photographers will enjoy reading about the determination and skill that went into creating a method they use every day in their craft.
"Explore the elements of composition, light, and direction that effectively create the illusion of time and motion in a digital image." The author explains how best to create these illusions and guides you through simple yet effective shooting techniques and post processing strategies.--[back cover].

Motion capture is one of the most talked about and misunderstood technologies in computer animation because of its rocketing popularity and ambiguous implementation. In Understanding Motion Capture for Computer Animation and Video Games , industry insider Alberto Menache tells the complete story of motion capture, examining its technical details as well as its growth as an industry. Menache's narrative voice and in-depth technical discussions allow the reader to not only learn motion capture, but also to understand the reasons behind its successes, failures, and increasing role in blockbuster films, such as Batman Forever and Batman and Robin . With its careful balance between technical analysis and industry trends, Understanding Motion Capture for Computer Animation and Video Games is the first book to explore the controversial art and practice of modern character animation using motion capture.
This volume explores the practicalities of how motion capture technology can be used creatively, beyond mere replication of live action. By focusing on what digital visual effects can learn from more established art forms like acting, keyframe animating and stagecraft, this book pushes the boundaries of what can be achieved with the hardware and software, to push the levels of performance, drama and audience engagement. This is an essential text for students who want to forge better appreciations of the mechanics and physicality of how we move and how we then re-interpret this knowledge via practical artistic forms of virtual expression and digital animation. We know that more control, more understanding of style and performance and storytelling is needed to master the visual technology, to capture and conjure designs, models and scenes. This book enables readers to construct better convincing movements, character animation and scenarios with 3D motion capture. A digital alchemist's path that leads, ultimately, from base models to captured moments of gold.

The CAPTECH'98 workshop took place at the University of Geneva on November 26–27, 1998, sponsored by FIP Working Group 5.10 (Computer Graphics and Virtual Worlds) and the Suisse Romande regional doctoral seminar in computer science. The subject of the conference was ongoing research in data capture and interpretation. The goals of capturing real world data in order to perceive, understand, and interpret them and then reacting to them in a suitable way are currently important research problems. These data can be very diverse: sounds, emotions, shapes, motions, forces, muscles, actions, etc. Once captured, they have to be treated either to make the invisible visible, or to understand a particular phenomenon so as to formulate an appropriate reaction, or to integrate various information in a new multimedia format. The conference included six sessions of presented papers and three panel discussions. Invited speakers treating various aspects of the topic were: Professor R. Earnshaw from Bradford University, Professor T. L. Kunii from Hosei University, and Professor P. Robert from EPFL. Professor K. Bauknecht, of the University of Zürich, President of IFIP, offered the welcoming address. Mr. E. Badique, project officer for the EU in Brussels, discussed recent results of the EU ACTS research program. Finally, the Geneva Computer Animation '98 Film Festival highlighted the evening of November 26.

Understanding Motion Capture for Computer Animation discusses the latest technology developments in digital design, film, games, medicine, sports, and security engineering. Motion capture records a live-motion event and translates it into a digital context. It is the technology that converts a live performance into a digital performance. In contrast, performance animation is the actual performance that brings life to the character, even without using technology. If motion capture is the collection of data that represents motion, performance animation is the character that a performer represents. The book offers extensive information about motion capture. It includes state-of-the-art technology, methodology, and developments in the current motion-capture industry. In particular, the different ways to capture motions are discussed, including using cameras or electromagnetic fields in tracking a group of sensors. This book will be useful for students taking a course about digital filming, as well as for anyone who is interested in this topic. Completely revised to include almost 40% new content with emphasis on RF and Facial Motion Capture Systems Describes all the mathematical principles associated with motion capture and 3D character mechanics Helps you budget by explaining the costs associated with individualized motion capture projects
