There are several color grading in different movies. Bese on these pictures, the short film color grades in different styles. However, there is no specific date for adjusting. The final result only relies on the feeling of the editor. It is notable that character’s face was also changed color when the editor did color grade. I watched some shared video about the color grade. However, they only show how to avoid this problem in other software instead of in premiere. For every frame, I did change the highlight, contrast, exposure, saturability.etc to fit the color.
