BLACK, WHITE, AND MID-POINT SLIDERS The Black, White, and Mid Point Sliders will automatically adjust the Curve for you. Black Point Slider Move the Black Point Slider to the right to set all luminosity values from the point you have selected and to the left to complete black (or to the absence of the channel's color when working on an individual color channel), while redistributing all of the values to stretch the luminosity range to match the entire possible range of values. It is recommended that you move the Black Point Slider all the way to the right to match up with the left-most information from the displayed histogram. This adjusts the current image so that the darkest values in the image match the darkest value that can be displayed in a digital file.

Decreasing the slope of the Curve will decrease the contrast in the image. The anchor points may also be set to minimize the amount of change that occurs to a tonal range of the image. Anchor points can be removed by simply clicking and dragging the anchor point outside of the Histogram. The Levels & Curves editor provides you with a number of additional controls: BLACK AND WHITE OUTPUT SLIDERS These two sliders enable you to set the maximum and minimum brightness levels of the image. By dragging the Black Output slider up, you lighten the darkest luminosity level in the image, and by dragging the white output Adjust Menu Chapter 22
