Inhalt:
"Forensic photography plays a vitally important part in the investigation of crime and the subsequent administration of justice. Written by a practitioner with many years professional experience, this book provides an overview of the most common forensic photography techniques in use today for those readers who may not have a detailed understanding of camera techniques and who need to get to grips with the use of light and other key scientific aspects of the job. It covers image capture issues, file handling and relevant equipment, such as lasers and UV lights, and explores how they work. The predominance of the digital camera has resulted in an increasing trend for police forces across the world to use untrained camera users, rather than expert photographers. Therefore, this book will prove invaluable for those practitioners who need to produce accurate and clear photographic evidence, above and beyond the point and shoot mode on their cameras."--
