Creating underpaintings
An underpainting is a version of the photo in which you adjust the photo’s colors, tones, and sharpness. The purpose of the underpainting is to prepare it for auto-painting. For example, you can darken colors to simulate the colors used in an 18th-century painting, or you can soften colors to simulate the colors found in watercolor paintings. After retouching a photo, you can clone it to prepare it for auto-painting. For more information about auto-painting, see Auto-painting photos.
Choosing an underpainting method
Depending on the effect you want to achieve, you can choose one of the following methods for creating an underpainting:
•
Quickly simulate the color and tone used in some popular art styles, such as watercolor paintings or chalk drawings, by using a
Color Scheme preset.
•
Match the color and tone of your underpainting to an existing image, such as a photo, scanned image, or digital artwork.
•
Quickly lighten, darken, or shift the color or contrast of your photo by using a
Photo Enhance preset.
•
Adjust individual settings in the
Photo Enhance area, and save the settings as a custom preset.
One method you can use to prepare a photo for painting (left) is to choose a source image (center) that contains the colors and tones you want to use. The color and tone of the source image can be applied to your photo to create an underpainting (right).
