Steal Light From Your Own Image: Aaron Nace's Channel-Based Lighting Trick
There’s a specific kind of frustration that comes from staring at a photo that’s almost great. The composition is solid, the subject is sharp, but the light feels flat and lifeless, like the scene was lit by a dentist’s office. I’ve been there more times than I’d like to admit, and my usual fix was to slap a Color Balance adjustment layer on it and hope for the best. Spoiler: it never looked great.
