What is S-Log?

With knee correction [3] Introduction to Picture Profile What is S-Log? The S-Log2 gamma curve is optimized to the dynamic range of the CMOS sensor. In order to bring out the contrast in highlights as much as possible, the sensor output has been extended to 1300% of the dynamic range. Although some color grading work is required, the S-Log2 gamma curve is an effective way to preserve highlight gradations that would otherwise be lost, thereby providing greater exposure latitude in recording.
