Tone-curve corrections
By selecting individual color channels on the tone curve, adjustments to the overall color of an image can be made. In this example, the image is too yellow. By moving the blue curve up, the image looks more neutral. For more on tone curve corrections, see page 60.
Selective-color palette
In the original image, the colors were muted making the whole scene flat. By subtracting cyan from the red channel, the bridge and faint details in the clouds could be accentuated. The cloud detail was further enhanced by subtracting yellow from the blue channel. For more on the selective- color palette, see page 71.
