Photoshop CS3 for Forensics Professionals: A Complete Digital Imaging Course for Investigators  (0470114541) cover image
Digital imaging technology has been used in forensics since at least 1992, yet until now there?has been?no practical instruction available to address the unique issues of image processing in an everyday forensic environment. Photoshop CS3 for Forensics Professionals serves the everyday, real-world needs of law enforcement and legal personnel dealing with digital images (including both photos and video stills). This book is an excellent tool for:

Law enforcement personnel, from crime scene and arson investigators, detectives, and patrol officers to forensic photographers, fingerprint examiners, video analysts, tool mark and footwear examiners, and criminalists.

Security pros in such fields as private investigation, insurance, fraud detection, and loss prevention.

Scientific and technical users of Photoshop with workflows similar to law enforcement, such as medical photographers, research imaging experts, engineering and architecture staff, and industrial photographers.

Staff responsible for maintaining a photo archive or printing images for court.

Photoshop CS3 for Forensics Professionals is the only book to provide forensics professionals with specific answers to their imaging questions. This is the perfect resource for those who want to move from simple theory to the essential skills needed to be more effective. This resource is dividied into three parts:

Part I: The Essentials is about setting up your workflow, archiving your images, and familiarizing yourself with Adobe Photoshop and Adobe Bridge, including the setting up of preferences. Also covered are the best practices in writing reports and providing courtroom testimony.

Part II: The Digital Darkroom teaches how to use Photoshop to accomplish what traditionally was done in the darkroom, from correcting color casts to making prints and exhibits for courtroom use.

Part III: Image Analysis & Enhancement covers techniques for clarifying images so that details can be better viewed and used for analysis or comparison, from contrast enhancement and pattern removal to even forensic video analysis.

The companion CD-ROM provides sample images—including various accident and crime scenes—you can use to practice the techniques from the book while?following along with the tutorials. It also includes several scripts, plug-ins, and actions so you can work more effectively.

In addition, instructor's materials are available so you can use book in workshops and training seminars.
