Historically, an underpainting was used to establish the overall color values for a painting. Similarly, the Underpainting panel lets you adjust the color, tone, and detail of a photo 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.
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).
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. You can use the following settings:
|
• |
Brightness — lets you brighten or darken the photo
|
• |
Contrast — lets you increase or decrease the difference in tone between the dark
and light areas of the photo
|
• |
Hue — lets you shift the color balance of the photo. For example, you can
correct a color cast or apply a cast to create a special effect.
|
• |
Saturation — lets you adjust the vividness of colors
|
• |
Value — lets you brighten or darken the photo by using the HSV color space
values
|
• |
Smart Blur — lets you adjust the level of detail in the photo. More detail is
maintained in high-contrast areas than in low-contrast areas.
