First stage of color grading that applies global adjustments to the entire image – corrects exposure, white balance, and color balance before targeted secondary corrections, establishing the foundational look.
What is Primary Grading?
Primary Grading is the first stage of color correction, where global adjustments are applied to the entire image. These fundamental corrections establish the technical and aesthetic foundation for further manipulation.
