Adjusting color and tone

CorelDRAW lets you adjust the color and tone of bitmaps. For example, you can replace colors and adjust the brightness, lightness, and intensity of colors.

By adjusting color and tone, you can restore detail lost in shadows or highlights, remove color casts, correct underexposure or overexposure, and generally improve the quality of the bitmaps. You can also correct color and tone quickly by using the Image Adjustment Lab. For information about the Image Adjustment Lab, see “Using the Image Adjustment Lab.”

You can adjust the color and tone of bitmaps by using the following filters.

Contrast enhancement
Lets you adjust the tone, color, and contrast of a bitmap while preserving shadow and highlight detail. An interactive histogram lets you shift or compress brightness values to printable limits. The histogram can also be adjusted by sampling values from the bitmap.
Local equalization
Lets you enhance contrast near edges to reveal detail in both light and dark regions. You can set the height and width around the region to accentuate contrast.
Sample/Target balance
Lets you adjust color values in a bitmap with sample colors taken from the image. You can choose sample colors from the dark, midtone, and light ranges of an image and apply target colors to each of the sample colors.
Tone curve
Lets you perform color corrections precisely, by controlling individual pixel values. By changing pixel brightness values, you can make changes to shadows, midtones, and highlights.
Lets you adjust the brightness of all colors and the difference between light and dark areas
Color balance
Lets you add cyan or red, magenta or green, and yellow or blue to selected tones in a bitmap
Lets you accentuate detail in low contrast areas without affecting shadows or highlights
Lets you adjust the color channels in a bitmap and change the position of colors in the spectrum. This effect allows you to change colors and their richness, as well as the percentage of white in an image.
Selective color
Lets you change color by changing the percentage of spectrum CMYK process colors from the red, yellow, green, cyan, blue, and magenta color spectrums in a bitmap. For example, decreasing the percentage of magenta in the reds spectrum results in a color shift toward yellow.
Replace colors
Lets you replace one bitmap color with another color. A color mask is created to define the color to be replaced. Depending on the range you set, you can replace one color or shift an entire bitmap from one color range to another. You can set the hue, saturation, and lightness for the new color.
Lets you reduce the saturation of each color in a bitmap to zero, remove the hue component, and convert each color to its grayscale equivalent. This creates a grayscale black-and-white photo effect without changing the color model.
Channel mixer
Lets you mix color channels to balance the colors of a bitmap. For example, if a bitmap has too much red, you can adjust the red channel in an RGB bitmap to improve image quality.
