In this tutorial, Apple Certified Master Trainer Simon Walker shows you how to work faster whilst grading using the Fill Light tool in Magic Bullet Looks, which can be more accurate than using the contrast sliders in Final Cutʼs 3 Way Color Corrector filter.
Editor's Note: Simon has asked me to point out that it is technically possible to use Final Cut to target selective areas of the shadows in an image by using the Limit Effect function of the 3 Way Color Corrector. It’s just that the Fill Light tool makes this easy, especially if you need to to make additional corrections within Magic Bullet Looks.
