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.
You can try grading with the free application Catalyst Browse, which has basic grading functions.
To run Catalyst Browse smoothly, an 8-core processor or similar operating environment is required.
