The rapid progress in science, technology, photography devices, the Internet, and social media has greatly contributed to the evolution of modern photographic tools. As a result, it has also empowered numerous individuals to explore their passion for photography. Recognizing this trend, I saw an opportunity to share my knowledge and experiences by writing a comprehensive book in photography, aimed at assisting aspiring photographers in gaining a deeper understanding of the art and techniques involved in capturing stunning landscapes and processing images.While the majority of the photos featured in the book were taken in the local area, specifically south coast in New South Wales, Australia, it also covers photos captured around the world, which complement the book's content, culminating in its completion. This book is structured to provide a helpful guide. It begins with a detailed exploration of photographic equipment, aiming to offer valuable insights and practical advice. Subsequently, it delves into the intricate mechanics of photography, covering essential topics such as camera optics, light, filters, colors, and more.After laying the foundation with an understanding of the fundamental technologies, this book introduces the essential knowledge about photography. These crucial topics encompass camera settings, composition techniques, lighting considerations, focus strategies, and more, each thoughtfully addressed in separate chapters. To enhance comprehension, these chapters are supplemented with a multitude of carefully curated examples.In an effort to provide comprehensive coverage, this book aims to encompass a wide range of topics, particularly focusing on photography in landscape photography. It endeavors to explore various aspects, techniques, and genres within photography, including but not limited to long exposure, panorama, seascape, nightscape, and astrophotography. By including these diverse areas, the book aims to equip readers with a well-rounded understanding and practical knowledge of different imaging techniques to enhance their skills and broaden their creative horizons.

ICICS'99, the Second International Conference on Information and C- munication Security, was held in Sydney, Australia, 9-11 November 1999. The conference was sponsored by the Distributed System and Network Security - search Unit, University of Western Sydney, Nepean, the Australian Computer Society, IEEE Computer Chapter (NSW), and Harvey World Travel. I am g- teful to all these organizations for their support of the conference. The conference brought together researchers, designers, implementors and users of information security systems and technologies. A range of aspects was addressed from security theory and modeling to system and protocol designs and implementations to applications and management. The conference con- sted of a series of refereed technical papers and invited technical presentations. The program committee invited two distinguished key note speakers. The ?rst keynote speech by Doug McGowan, a Senior Manager from Hewlett-Packard, USA, discussed cryptography in an international setting. Doug described the current status of international cryptography and explored possible future trends and new technologies. The second keynote speech was delivered by Sushil Ja- dia of George Mason University, USA. Sushil's talk addressed the protection of critical information systems. He discussed issues and methods for survivability of systems under malicious attacks and proposed a fault-tolerance based - proach. The conference also hosted a panel on the currently much debated topic of Internet censorship. The panel addressed the issue of censorship from various viewpoints namely legal, industrial, governmental and technical.

This monograph illustrates important notions in security reductions and essential techniques in security reductions for group-based cryptosystems. Using digital signatures and encryption as examples, the authors explain how to program correct security reductions for those cryptographic primitives.
