About Highlight tone priority
- With setting [1: Enable], improves the highlight detail. The dynamic range is expanded from the standard 18% gray to bright highlights. The gradation between the grays and highlights becomes smoother.
- With setting [1: Enable], noise (grainy image, banding, etc.) may become slightly more pronounced than with setting [0: Disable].
