About this title

Review:

This technical guide to scanners helps potential buyers, reviewers, engineers, and scientists understand what traits to look for in a scanner and how to make the best scans possible. The focus is on image scans rather than document scans. The book discusses topics such as types of scanners, scanning software, hardware interfaces, accessories, digital cameras, and the technologies behind optical-reduction, contact-image sensor, color-separation, transmissive-filter, light-source separation, and beam-splitting scanners.

As author Robert G. Gann explains how to create good scans, he explores such issues as exposure controls, scanning speed, resolution, interpolation, image noise, illumination, color registration and fidelity, and black-and-white output. He also recommends several tests for scanners and provides a glossary of scanner terms and a full-color section of images of sample scans.

The companion CD-ROM comes with sample images, test results, and a spreadsheet for RGB-to-LAB conversion. The book doesn't recommend specific brands or models, but has all the technical detail that a private consumer, corporate buyer, or reviewer needs to make an informed decision on today's scanners. --Kathleen Caster

From the Back Cover:

The “no-hype” expert guide to choosing your next scanner.

Bewildered by today's complex scanner specs? Need to filter the hype from the reality? Desktop Scanners: Image Quality Evaluation delivers the practical, objective information you need to choose the best scanner — and get great results from it. Detailed enough for experts yet clear enough for beginners, it's like having a world-class scanning expert by your side throughout the entire evaluation, purchase and configuration process. You'll get answers to key questions like:

• What kind of scanner do I need? Are those new low-cost scanners really enough?
• How does a scanner actually work, and how can I make mine work better?
• What do those DPI and bit-depth specifications mean — if anything?
• How do I scan for accurate color on the Web?
• What options and software do I need?
• How are scanners changing, and which new technologies are most important?

From the absolute basics to sophisticated gamma correction and color space issues, here are the practical answers and step-by-step testing procedures you need to get the most for your money. When it comes to scanners, you'll never be “in the dark” again.

On the accompanying CD-ROM, you'll find example images, scanner evaluation tools, online presentations, and further explanations of key concepts.
