Introduction: This tip sheet introduces the technical structure of a digital image and explains the measures for digital image characteristics. The focus is on images created by digitizing photographs, including negatives, transparencies, and prints by using steganography. Methodology: The process of capturing a rich digital master image that achieves “Best Practice” standards in the categories noted here depends upon a variety of factors including: quality of the equipment and software, quality control processes, operator skill, and technical and administrative support throughout the process, including management of the digital image and its metadata once the digital image is created. Consulting current standards can provide the information necessary to establish a system for the digitization of photographs. Once a system is in place, benchmarking the capabilities (and understanding the limitations) of that system through testing and exploration by using targets and a sampling of representative materials will better insure a quality result in the digital images that are created. Objectives: Understanding digital image elements can help you plan effective scanning services and create rich digital master images. Result: The headlong development that has characterized the digital world from its very inception has not been even in all its parts: some issues have been relatively neglected and have not kept up with rapid technical and market changes. Among these are questions relating to digital identity, data security, and consumer privacy. With all the expansion in progress in this domain, and the constant innovation, the risks involved are magnified and thus assume an increasing urgency. Matters such as social participation and interaction in the digital environment are equally important to consider as they ultimately provide the backdrop for developments in this field. This chapter examines the rapidly changing technological and social environment surrounding the individual (later referred to as the “digital individual”), and the blurring boundaries between the public and private spheres of existence. Detailed consideration is then given to the establishment and management of digital identity online. Implication: People use digital images in many ways. The same image can be viewed on a wide variety of monitors, printed in many formats, and transmitted electronically through e-mails, cell phones, and other systems.
