Adjusting Histogram Tone Levels

You can use a histogram tool to adjust the tone shadow for the preview image.

Using the eyedroppers, you can sample the black-point, mid-point, and white-point tone in the preview image and base the image tone settings on the sampling. Using the corresponding text boxes, you can type a value in the Black-point, Mid-point, and White-point text boxes.

Eyedropper

Under the histogram chart, you can slide the black, grey, and white buttons to adjust the tones. However, you cannot edit the histogram directly.

When you adjust the black-point, all tones in the image darker than the selected black-point are adjusted to black.

When you adjust the mid-point, all tones in the image between the black- point and the white-point are adjusted to the selected mid-point.
