You can use the Advanced method to more accurately adjust colors using the curve. You can adjust the 1/4 Tone, Midtone, and 3/4 Tone ranges by manually dragging the curves of red, green, and blue. You can also adjust color by setting the percentage of red, green, and blue at five specific points in the curve: Highlight, 1/4 Tone, Midtone, 3/4 Tone, and Shadow.
Each section of the curve controls the balance between the shadows, midtones, and highlights of an image. Setting values in the upper portion of the grid lightens the image; whereas setting values in the lower portion of the grid darkens the image.
Various tone curves were modified to achieve this look.
You can compare the adjusted image with the original image by enabling and disabling the Preview check box.
