Lynda.com 出品的 Photoshop CS3 教程，掌握 LAB 色度空间，Deke McClelland 主讲。

CIE 于 1976 年时制定了一个均匀的 CIE LAB 色彩空间（CIE 1976 L*a*b* ）。在 CIE L*a*b* 色彩空间中，色彩的刺激值是以色相（Hue）、彩度（Chroma）及明度（Lightness）三种感知属性（Perceptual attribute）来表示。在使用 Lab 颜色执行某些类型的颜色更改时，其结果将比使用 RGB 颜色更快更好。在本教程中，Deke McClelland 探讨了如何利用 Lab 颜色对照片进行处理，通过一个典型的非破坏性的 Lab 色彩校正，展示了最适合的图像处理方法。同时说明了如何正确的利用光照系统，应用于选择颜色的修改，并校正色偏。教程内附练习文件。

Photoshop CS3 Mastering Lab Color
with: Deke McClelland

Based on the device-independent CIE specification from 1976, Lab color is frequently misrepresented as a techy, labor-intensive color space. In fact, Lab color performs certain types of color modifications more quickly and with better results than RGB. In Photoshop CS3 Mastering Lab Color, Deke McClelland explores how to use Lab color "to make bad photographs great and great photographs even better." He demonstrates image manipulations that are best suited to Lab, and walks through a typical, non-destructive Lab correction. Deke also shows how to correct lighting, apply selective color modifications, and reverse the effects of color cast. Exercise files accompany the course.
