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 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?
