Matching Shots - The Art and Technique of Digital Color Correction - page 377

With the buildings matching fairly close, Falcon pulls a secondary HSL
key for the lion and matches it as well ( Figures 9.28 - 9.30 ). She also adds
a simple HSL qualification to both the images to correct for the clipped
sky. Those corrections are nearly identical to those done by the previous
colorists in this chapter.
Falcon offers a final tip at the end of her matching session: “A lot of
color correction is about defining edges and contrast and being able to see
what you want to see.”
