What is grading?

Applicable Products and Categories of This Article

Grading is post-production image processing performed to adjust the contrast and coloring.

To allow for grading and flexible expression, videos must be shot with a wide dynamic range and wide color reproduction range. The S-Log gamma curve and S-Gamut color reproduction are used to record these kinds of videos. Without grading, videos recorded with S-Log2 or S-Log3 have low contrast and saturation because these videos are supposed to be graded after recording.
