The Sample/Target balance filter lets you shift the tonal range of an image by sampling specific image areas. The Histogram equalization filter lets you view the tonal range of an image and redistribute the balance of shadows, midtones, and highlights in the composite channel or in individual color channels according to a preset histogram model. The filter uses neighboring pixels to create a stylized effect.

The Local equalization filter lets you enhance the contrast near image edges and reveals details in both light and dark regions. The histogram can also be adjusted by sampling values from the image. An interactive histogram lets you shift or compress brightness values to printable limits. The Contrast enhancement filter lets you adjust the tone, color, and contrast of an image while preserving shadow and highlight detail that is lost when you adjust the brightness, contrast, and intensity of an image. This adjustment is performed on each color channel of the image, resulting in changes to the color and tone of the image. The Auto adjust filter equalizes the shadows, midtones, and highlights in an image by automatically redistributing the significant pixel values throughout the tonal range. For more information about using lenses, see Working with lenses. Many of these filters are also preset lens types. However, most of these filters are advanced tools that give you greater control over the image correction process or let you change colors for specific effects. Some of these filters offer the same controls that can be found in the Image Adjustment Lab. Ĭorel PHOTO-PAINT provides you with many filters to adjust the color and tone of images.
