Chapter 20 — Adjust Menu | Color > LCH 191

The Master Lightness channel provides you with the following controls:

q Curve Editor

The curve editor is where the majority of the enhancements are made within the

LCH feature. Within the curve editor, you are presented with a histogram that

represents the total luminosity values within your image. A luminosity curve

superimposed above this histogram enables you to control the relationship of

input luminosity values to output luminosity values.

The histogram displays a bar graph representing the total number of pixels that

appear at different levels of luminosity. The horizontal axis represents the

luminosity level, while the vertical axis represents the number of pixels at each

luminosity level found within the current image. The left side of the horizontal axis

represents the darkest tones of your image, while the right side represents the

lightest tones in the image. The histogram is very helpful in determining how to

adjust the settings within the Master Lightness channel.

Click directly on the luminosity curve to add an anchor point that can be moved

and adjusted. By increasing the slope of the curve, you will increase the contrast in

the image. 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 curve editor.
