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

qCurve Editor 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.
