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
