A gradient map is a smooth blending from one color to another. The Gradient Map adjustment in Photoshop converts existing colors to a gradient based on whether the area is a dark, mid-tone, or light color. The dark color becomes the color to the left of the gradient map, the light color becomes the color to the right of the gradient map, and a mid-tone becomes a blend of the colors. By using gradient map, you can transform your picture into an attractive duotone image or a rainbow image that looks very wacky.
How to Make a Gradient Map in Photoshop
- From the Tools panel, pick two colors for the gradient.
- The foreground color swatch sets the dark colors. Pick a dark color such as dark blue or dark green.
- The background color swatch sets the light colors. Pick a light color such as light blue or light green or white.
- The mid-tones will become a blend of those two choices.
