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 adjusting these elements, you must clone the underpainting to preserve it and to prepare for auto-painting. Creating a clone allows Corel Painter to borrow colors from the photo in order to recreate it as a painting on a blank canvas.

Depending on the effect you want to achieve, you can choose one of the following methods for creating an underpainting:
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).
