The role of the curve:

The curve is an important tone and tone adjustment tool. It can:

1. Adjust the overall or Contrast of individual channels;

2. Adjust the brightness of any part;

3. Adjust the color.

The basic principle of the learning curve:

Input: horizontally at the bottom of the coordinates is the input, which displays the color information on the current picture.

Output: The vertical line is the output line, which allows us to adjust the output result of the picture.

There is a light and dark information on the input and output axes, telling us which side is the shadow and which is the highlight. When we adjust, we adjust the image based on this information.

Control points:

Click the mouse on the curve to add control points. We use the control points to adjust the position of the curve to change the color and saturation of the image. We can add multiple control points on the curve to achieve the effect we want.
