The silver-based emulsion and chemical process used successfully for many years for the capture and storage of images has now largely been superseded by the introduction of digital technology. The widespread use of digital cameras among imaging professionals, archaeologists and the general public has created a vast array of digital information. If this information is to be of use now and for future generations, it requires the application of a systematic approach to how it is captured and stored. Digital technology is still in its infancy compared with the long-established technique of using silver-based emulsions on glass plate or film to produce images that have, with suitable development and storage, proven to be stable and enduring. Some would argue that our records should still be made in this way, but film is becoming more difficult to source. In addition, film-processing laboratories are disappearing from our high streets, making local processing a thing of the past in all but the largest cities. The tide has turned in favour of digital image capture, which offers many benefits that offset its unproven longevity. However, part of the problem with the digital environment is that its boundaries and possibilities are constantly changing. This publication offers guidance on digital image capture and storage to assist those involved with the making and keeping of images of the historic environment. It does not provide definitive answers regarding the problems of taking and storing digital images but does provide an overview of current recommendations.

"The first edition of Introduction to Imaging was published in 1995 and quickly became a standard textbook on the construction of digital image collections. The Visual Resources Association Bulletin praised it for setting forth "important basic principles and technical terms that anyone beginning an imaging project would need to know."" "Significantly expanded and updated, the revised edition of Introduction to Imaging allows curators, librarians, collection managers, scholars, and students to better understand the basic technology and processes involved in building a cohesive set of digital images. It also explores how to link digitized images to the information required to access, preserve, and manage them. Other topics include making data interoperable with other information resources and activities; developing strategies that do not limit or foreclose future options; and ensuring the longevity of digital assets.

The major function of photography is to capture a picture from what is in front of you. Whether a picture of the family pet or advertising spread, the acquisition of the scene is the first step in the digital image process. Digital Photographic Capture takes that first step and it breaks it down in detail so you can understand and better manipulate the mechanics of the process. As we transition from the silver halide base of photography to an electronic enabled future, we can step to the side and look at the intersection of these processes. Today it is not that one is superior in all situations, but that in the imaging world hybrid imaging maintains uses in unique applications and has certain advantages. Digital Photographic Capture explores construction and functions of the various parts and processes used to capture images. Sensors, lenses, creation, storage, and hybrid imaging are all broken down into basic explanations, enabling the photographer to have a basic understanding of the photography today. This is your new introduction to photography.

Photographic imagery has come a long way from the pinhole cameras of the nineteenth century. Digital imagery, and its applications, develops in tandem with contemporary society’s sophisticated literacy of this subtle medium. This book examines the ways in which digital images have become ever more ubiquitous as legal and medical evidence, just as they have become our primary source of news and have replaced paper-based financial documentation. Crucially, the contributions also analyze the very profound problems which have arisen alongside the digital image, issues of veracity and progeny that demand systematic and detailed response: It looks real, but is it? What camera captured it? Has it been doctored or subtly altered? Attempting to provide answers to these slippery issues, the book covers how digital images are created, processed and stored before moving on to set out the latest techniques for forensically examining images, and finally addressing practical issues such as courtroom admissibility. In an environment where even novice users can alter digital media, this authoritative publication will do much so stabilize public trust in these real, yet vastly flexible, images of the world around us.
