Using the Image Adjustment Lab

The Image Adjustment Lab lets you correct the color and tone of most photos quickly and easily.

The Image Adjustment Lab consists of automatic and manual controls, which are organized in a logical order for image correction. By starting in the upper-right corner and working your way down, you can select the controls you need to correct the problems specific to your image. It is best to crop or retouch any areas of the image before beginning the color and tone corrections. For information about cropping and retouching images, see Cropping images and Retouching.

While you work in the Image Adjustment Lab, you can take advantage of the following features:


1. Rotation tools

5. Select white point

9. Sliders

2. Pan tool

6. Select black point

10. Hint for current tool

3. Zoom tools

7. Undo, Redo, and Reset

11. Histogram

4. Preview Modes

8. Snapshots


Using automatic controls

You can begin by using the automatic correction controls:

Using color correction controls

After using the automatic controls, you can correct color casts in your image. Color casts are typically caused by the lighting conditions when a photo is taken, and they can be influenced by the processor in your digital camera or scanner.

Correction of a color cast depends on the type of light that caused the cast. The image on the left was taken indoors in incandescent light. The image on the right is the corrected version.

Adjusting brightness and contrast across the entire image

You can brighten, darken, or improve the contrast in an image by using the following controls:

Adjusting the brightness and contrast of an image can reveal more image detail.

Adjusting highlights, shadows, and midtones

You can brighten or darken specific areas of an image. In many cases, the position or strength of the lighting at the time a photo is taken causes some areas to appear too dark and other areas to appear too light.

The Highlights and Shadows sliders can lighten or darken specific areas of an image.

Using the histogram

The histogram lets you view the tonal range of an image to help you evaluate and adjust the color and tone. For more information about the histogram, see Using histograms.

Viewing images in the Image Adjustment Lab

The tools in the Image Adjustment Lab let you view images in various ways, so that you can evaluate the color and tone adjustments you make. For example, you can rotate images, pan to a new area, zoom in or out, and choose how to display the corrected image in the preview window.

Using other adjustment filters

Although the Image Adjustment Lab lets you correct the color and tone of most images, a specialized adjustment filter is sometimes required. Using the powerful adjustment filters in Corel PHOTO-PAINT, you can make precise adjustments to images. For example, you can adjust images by using a histogram or a tone curve. For more information about adjustment filters, see Using individual color-adjustment effects and tools.
