First developed in the 1880s as a way to monitor glaciers in Europe, repeat photography —the practice of taking photographs at different points in times from the same physical vantage point—remains an essential and cost-effective technique for scientists and researchers working to track and study landscape change. This volume explores the technical and geographic scope of this important technique, focusing particularly on the intertwined influences of climatic variation and land-use practices in sculpting landscapes. Contributors offer a broad-perspective review of the state-of-the-art of repeat photography, with twenty-three chapters written by researchers around the globe who have made use of repeat photography in their work. Topics addressed include the history of repeat photography techniques for creating and analyzing repeat photographs applications in the geosciences applications in population ecology applications in ecosystem change cultural applications Repeat Photography demonstrates the wide range of potential applications, examines new techniques for acquiring data from repeat photography, and clearly shows that repeat photography remains a valuable and efficient means of monitoring change in both developed and developing regions. Over one hundred sets of photographs, including thirty-two pages of color photos, serve as examples. Recent concerns about climate change and its effects on natural landscapes, combined with ongoing concerns about land-use practices, make this state-of-the-art review a timely contribution to the literature.
As the need for geographical data rapidly expands in the 21st century, so too do applications of small-format aerial photography for a wide range of scientific, commercial and governmental purposes. Small-format Aerial Photography (SFAP) presents basic and advanced principles and techniques with an emphasis on digital cameras. Unmanned platforms are described in considerable detail, including kites, helium and hot-air blimps, model airplanes, and paragliders. Several case studies, primarily drawn from the geosciences, are presented to demonstrate how SFAP is actually used in various applications. Many of these integrate SFAP with ground-based investigations as well as conventional large-format aerial photography, satellite imagery, and other kinds of geographic information. - Full-color photographs throughout - Case studies from around the globe - Techniques presented allow for image resolution impossible to match via traditional aerial photography or satellite datasets - Glossary clarifies key terms
Small Format Aerial Photography and UAS Imagery: Principles, Techniques and Geoscience Applications, Second Edition, provides basic and advanced principles and techniques for Small Format Aerial Photography (SFAP), focusing on manned and unmanned aerial systems, including drones, kites, blimps, powered paragliders, and fixed wing and copter SFAP. The authors focus on everything from digital image processing and interpretation of data, to travel and setup for the best result, making this a comprehensive guide for any user. Nine case studies in a variety of environments, including gullies, high altitudes, wetlands and recreational architecture are included to enhance learning. This new edition includes small unmanned aerial systems (UAS) and discusses changes in legal practices across the globe. In addition, the book presents the history of SFAP, providing background and context for new developments. - Provides background and context for new developments in SFAP - Covers the legal implications for small format aerial systems in different countries - Discusses unmanned aerial systems (drones) and their applications - Features new case studies for different applications, including vineyard monitoring and impacts of wind energy
Computational photography refers broadly to imaging techniques that enhance or extend the capabilities of digital photography. This new and rapidly developing research field has evolved from computer vision, image processing, computer graphics and applied optics—and numerous commercial products capitalizing on its principles have already appeared in diverse market applications, due to the gradual migration of computational algorithms from computers to imaging devices and software. Computational Photography: Methods and Applications provides a strong, fundamental understanding of theory and methods, and a foundation upon which to build solutions for many of today's most interesting and challenging computational imaging problems. Elucidating cutting-edge advances and applications in digital imaging, camera image processing, and computational photography, with a focus on related research challenges, this book: Describes single capture image fusion technology for consumer digital cameras Discusses the steps in a camera image processing pipeline, such as visual data compression, color correction and enhancement, denoising, demosaicking, super-resolution reconstruction, deblurring, and high dynamic range imaging Covers shadow detection for surveillance applications, camera-driven document rectification, bilateral filtering and its applications, and painterly rendering of digital images Presents machine-learning methods for automatic image colorization and digital face beautification Explores light field acquisition and processing, space-time light field rendering, and dynamic view synthesis with an array of cameras Because of the urgent challenges associated with emerging digital camera applications, image processing methods for computational photography are of paramount importance to research and development in the imaging community. Presenting the work of leading experts, and edited by a renowned authority in digital color imaging and camera image processing, this book considers the rapid developments in this area and addresses very particular research and application problems. It is ideal as a stand-alone professional reference for design and implementation of digital image and video processing tasks, and it can also be used to support graduate courses in computer vision, digital imaging, visual data processing, and computer graphics, among others.

Digital Ultraviolet and Infrared Photography discusses the growing number of applications of ultraviolet and infrared photography. Scientific and technical photographers, such as those engaged in scientific, medical, forensic, and landscape and wildlife photography routinely use ultraviolet and infrared techniques, and these techniques are growing in use in creative photography. This is the first book to address the application and potential for both ultraviolet and infrared photography in both science and art. The author, Adrian Davies, discusses the how-to of ultraviolet and infrared digital recording with a dissection of techniques, camera requirements and camera conversion, a useful appendix of resources and equipment currently available and inspirational image examples throughout. Digital Ultraviolet and Infrared Photography is an essential read for photographers using these tools either professionally or creatively.
