ESSENTIAL COLOR MANAGEMENT, PHOTOSHOP CS3
AN E-BOOK BY GRY GARNESS
This 50-page e-book has evolved from a Photoshop course handout to a comprehensive resource full of practical advice, for all of you who can't take the mind-numbing science of color management. It's worded as down-to-earth as possible without dummifying the content. It's aimed at professional image-makers who need to deliver high-standard images for reproduction, and be confident that their workflow follows good practice. It reveals what lies behind the industry jargon, specifications and definitions.
The book gives useful recommendations on calibration, color spaces, printing, paper types, viewing lighting, web output and much more. It offers straightforward advice – not just an overwhelming myriad of options. If you're in the business of supplying images for print reproduction, or even just producing inkjet prints, this is the book for you.
