2 In the Color Correction dialog box, choose Curve from the list box.
3 Click one of the following color buttons:

• Green — allows you to adjust only the green curve
• Blue — allows you to adjust only the blue curve
• Master — allows you to adjust all color curves at once
4 Drag the Effect slider to the right to increase the range of the curve that’s affected
when you drag it, or drag it to the left to decrease range.

shadows and dragging it up increases highlights.
