Scanning

Real World Scanning and Halftones (3rd Edition) (Real World)

This highly useful, detailed guide helps desktop-publishing and other design professionals produce the best possible scans and halftones from their images. The first section focuses on scanning, first featuring explanations of such terms as spi (samples per inch), bit depth, optical and interpolated resolution, and dynamic range. The authors even advise you on buying and cleaning scanners. Next they detail the elements of good scans and how to fix less-than-perfect ones, helping you figure out what sort of file formats and resolutions to use in your work, how to do tonal and color corrections, and how to sharpen and compress images. Finally, the discussion turns to Web and printer output and to OCR technology and PhotoCD images.

The section on halftones teaches you how to produce decent halftone images, first by explaining how halftones work and then by explaining such issues as frequency, gray levels, spot variation, spot gain, spot shapes, and the role of printers and software in creating halftones. There's also a discussion of stochastic screening and how to create blends and reduce moiré and other patterns. The last chapters here help you fine-tune your halftone settings and learn a bit about PostScript operators for halftones and scanning.

The third and last section focuses on using image applications to work with scans, tonal and color corrections, and halftones. This discussion includes Adobe Photoshop, Micrografx Picture Publisher, Corel Photo-Paint, Ulead PhotoImpact, Equilibrium's DeBabelizer, Adobe Illustrator, Macromedia FreeHand, CorelDRAW, Adobe PageMaker, and QuarkXPress. The authors also look at a few scanning applications and offer tips on using them.

Throughout the book the authors provide plenty of images and screen shots to illustrate their points, and a full-color section helps bring some of these examples to life. There's lots of technical discussion, but since each chapter builds on the previous ones and the basic terminology is put forth clearly, you can leave off wherever you wish and still have a lot of new knowledge to apply to your scans and halftones. --Kathleen Caster

Scanners for Dummies

Digital cameras have encroached upon the territory of scanners a little bit, but scanners remain eminently useful for digitizing the family photo album, archiving documents, and sending kids' artwork to distant family members. They're also absolutely essential for serious design work. Scanners for Dummies shows you how to get the most from your scanner by guiding you through everything from basic hookup and software installation to moderately advanced graphics-editing techniques. The author, Mark Chambers, patiently explains terminology and concepts that have to do with translating a physically recorded image (such as a photograph) into a digital file (such as a JPEG or GIF image).

Most readers will be able to get a lot from this book by simply reading chapters straight through, since the explanations of traditionally nebulous concepts such as resolution and color depth are accurate and easy to follow. Even the quality of the illustrations--often a shortcoming of trade computer books--is high, which is important in sections that show how to adjust contrast, sharpness, and resolution. Chambers deserves kudos for doing many of his tutorials in Jasc Paint Shop Pro, an excellent yet inexpensive editing package. Some readers might prefer coverage of one of the freebie editing suites; they should look for a software-specific book to supplement this one. --David Wall

Topics covered: Digitizing images via a scanner connected to a computer running Microsoft Windows. Hardware connectivity (via parallel, SCSI, USB, and FireWire) is covered before the author explains the scanning procedure and how to manipulate images in an editing program. Suggestions for craft projects and some troubleshooting tips round out the volume.

Avoiding the Scanning Blues: A Desktop Scanning Primer

The human eye can perceive about 5,000 shades of gray, points out Avoiding the Scanning Blues: A Complete Guide to Desktop Scanning. By the time a real-life scene has been photographed, printed on photographic paper, and scanned, it has been reduced to 250 shades of gray, at best. Laser printing usually reduces the palette further, to 125 shades. The challenge of the professional graphic artist is to use the scanner properly to minimize the effect of this technical limitation. With an emphasis on that goal, this book explains techniques for professional scanner use. It treats scanners as the powerful tools that they are, and not merely toys for attaching photographs in e-mail messages. This book is one of very few that take scanner work seriously, and it's definitely worth buying if you're a professional or avid amateur scanner of images.

Most chapters begin with clear explanations of concepts; the logic being that you can't get far as a manipulator of images if you don't know what terms mean, or what effects various pieces of the imaging chain have on the end product. The style is concise and readable (although, for clarity, mathematical equations should have been set out from the body text), and illustrations ("good" and "bad" sample photos, plus screen shots) enhance the text. Easy-to-follow how-to passages appear throughout, most of which have to do with aspects of Adobe Photoshop. The book challenges you to scan practice images that have problematic visual characteristics and fix some intentionally bad originals. --David Wall

Topics covered: Scanning for professionals, with an emphasis on getting the highest possible printed product from the originals at hand; in-depth coverage of evaluating an image to be scanned, performing the scanning process, and performing filtering and other manipulations on newly digitized images; also, the specifics of transparency and negative scanning, as well as of digital image theory.

Multidetector-Row Computed Tomography: Scanning and Contrast Protocols

Multidetector-row computed tomography (MDCT) has advanced the approach to diagnostic assessment of many pathologies and now plays an integral role in imaging of both abdominal and cardiovascular diseases. The possibility to acquire diagnostic images with shorter scan duration, longer scan ranges, and/or thinner sections, MDCT has facilitated the opening of new horizons, such as interventional MDCT and functional imaging in stroke and oncology. In addition, advanced postprocessing techniques now permit high quality volumetric imaging in combination with maximum intensity projections, volume rendering, curved planar reformations and multiplanar reconstructions. This volume gathers contributions by internationally renowned specialists in the field who, through presenting their clinical experience, provide a thorough overview not only of MDCT and its practical applications, but also of workflow management in everyday clinical practice. Focussing on scanning and contrast protocols, the current advantages and disadvantages of non-enhanced vs. enhanced MDCT are discussed, along with insights into likely future developments. The volume represents an up-to-date source of technical and practically-oriented clinical information which should prove of great benefit to all who wish to improve or consolidate their knowledge and expertise in MDCT.

Scanning Negatives and Slides: Digitizing Your Photographic Archives

Many photographers have either moved into digital photography exclusively or use both analog and digital media in their work. In either case, there is sure to be an archive of slides and negatives that cannot be directly integrated into the new digital workflow, nor can it be archived in a digital format. Increasingly, photographers are trying to bridge this gap with the use of high-performance film scanners.

In this 2nd edition, you will learn how to achieve the best possible digital image from a negative or a slide, and how to build a workflow to make this process efficient, repeatable, and reliable. The author uses Nikon's film scanners, but all steps can easily be accomplished while using a different scanner. The most common software tools for scanning (SilverFast, VueScan, NikonScan) are not only covered extensively in the book, but are also provided on a DVD, which also contains other useful tools for image editing, as well as numerous sample scans.

Start With a Scan: A Guide to Transforming Scanned Photos and Objects into High Quality Art

The art of mixed media has taken on new meaning in the digital production environment, and the second edition of Start with a Scan guides new artists through the maze of image acquisition, hardware, and software toward the goal of final output. This is not just a book on scanning and creating art, but about the art and science of scanning, editing, and tailoring an image to your needs, too.

Beginning by explaining how scanners work, the different types of scanners that are out there, and why it's important to know how the scanned image will be used, the book quickly digs into the meat and potatoes of editing, altering, tracing, and otherwise changing a scanned image to suit a project.

Arguably the most interesting chapters are "Creating Textures and Backgrounds from Print and Paper" and "Transforming Photos into Graphics." One of the most difficult and time-consuming tasks that a designer faces is finding and creating background elements and graphics. In these two chapters, which probably are worth the cover price alone, Scan explains how to use scanned photos or raw elements (cloth, paper, and so on) to create the element that you need.

Although the book deals with digital tools (e.g., scanners and computers), it hardly could be called a computer graphics book. The goal is teaching how to scan and alter images, and Scan never loses sight of that. The authors deserve a great deal of credit for creating what is an educational and inspirational book on a form of visual art that happens to use computers as tools, instead of a computer book that happens to talk about digital graphics. This is how books of the genre should be written. --Mike Caputo
