TONE CURVES AND HISTOGRAM

SETTING THE WHITE, BLACK OR GREY POINTS

White point (highlight point) indicates the section you want to lighten, Black point (shadow point) the section you want to darken, and Grey the section you want to have as neutral tone. An image with no highlight or shadow will not be clear and appear dull. You can correct the image by adjusting the White point/Black point/Grey point buttons to enhance the highlight or shadow point so that the image will have good contrast

and not be all white or black. Also if the image has too much contrast, you can correct it by weakening the highlight or shadow point.

•Changes are automatically applied to the prescan image.
