How do I use Paint On Adjustments

This section provides information on the following topics:

Use the image adjustment editor

You can use the Image Adjustment Editor to quickly and easily adjust the color and tone of most photos.

The Image Adjustment Editor offers automatic and manual correction options arranged in a logical order for image correction. If you start by selecting the correction options in the upper right corner and then work your way down, you can select the options necessary to fix the specific problems in your image. Before beginning any color and tone adjustments, you should crop and retouch the image as needed. For more information on cropping and retouching images, see Cropping and Retouching Images.

When working in the image adjustment editor, you can use the following functions:

Take a snapshot: You can keep the corrected version of an image in a "snapshot" at any time. Thumbnails of the snapshots are displayed in a window below the respective image. Snapshots allow different corrected versions of an image to be compared and thus help to select the best image.
Undone, Restore and Reset to original: Most image correction is a trial and error approach. It is therefore important that corrections can be undone and redone. The command Reset to original clears all corrections so you can start over.


Use automatic correction options

You can start correcting the image using the automatic correction options:

Automatic adjustment: Contrast and color of an image are automatically corrected by determining the lightest and darkest areas and by adjusting the tonal range for each color channel. For some images, this option is sufficient to enhance the image. If not, you can undo the changes and use more precise correction options.
Choose white point: Automatically adjusts the contrast in an image based on the set white point. With the aid Choose white point For example, you can lighten an image that is too dark.
Choose black point: Automatically adjusts the contrast in an image based on the specified black point. With the aid Choose black point For example, you can make an image that is too bright darker.

Use color correction options

After using the automatic correction options, you can correct color casts in the image. Color casts are usually caused by the lighting conditions when taking a photo and can be influenced by the processor of the digital camera or the scanner.

temperature: Corrects color casts by "heating" or "cooling" the color in the image to compensate for the light conditions when the photo was taken. Example: To correct a yellow-tinged indoor photo that was taken in a low-light incandescent lamp, you can move the slider towards the blue end to increase the temperature values ​​(in Kelvin). Lower values ​​correspond to poorer lighting conditions, such as candlelight or incandescent light, which can cause a yellow tinge. Higher values ​​correspond to better lighting conditions, such as sunlight, which can cause a blue cast.
tint: Corrects color casts by adjusting the green or magenta values ​​in an image. You can make the image greener by moving the slider to the right and redder by moving the slider to the left. By moving the slider tint after adjusting the controller temperature you can fine tune an image.
saturation: Allows you to adjust the color intensity. For example, moving the slider to the right can make the blue of the sky more vivid in an image. You can reduce the color intensity by moving the slider to the left. By moving the slider all the way to the left so that all color is removed from the image, you can create a black and white photo effect.

Correcting color casts depends on the type of light that caused the color cast. The picture on the left is an indoor shot taken under incandescent light. The picture on the right shows the corrected version.

Adjust brightness and contrast throughout the image

You can lighten, darken, or improve the contrast of an image using the following correction options:

brightness: Lighten or darken the entire picture. This option can correct exposure problems caused by too much light (overexposure) or too little light (underexposure) when the photo was taken. If you want to lighten or darken certain areas of an image, you can use the sliders Highlights, shadow and Midtones use. The adjustment made with the controller brightness is not linear, so the current values ​​for the white point and black point are not affected.
contrast: Increases or decreases the difference in tint between the dark and light areas of an image. Moving the slider to the right makes the light areas lighter and the dark areas darker. For example, if the image appears dull and low in contrast, you can sharpen the details of the image by increasing the contrast.

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

Adjust highlights, shadows, and midtones

You can lighten or darken certain areas in an image. For many images, the location or level of lighting when the photo was taken will cause some areas to appear too dark and others too light.

Highlights: Adjusts the brightness in the lightest areas of an image. For example, if you've taken a photo with the flash and the objects in the foreground appear washed out by the flash, you can use the slider Highlights move left to darken the washed out areas of the image. You can use the regulator Highlights together with the controls shadow and Midtones use to compensate for the lighting.
shadow: Adjusts the brightness in the darkest areas of an image. Example: A bright lamp behind a recorded object (backlight) can cause the object to be in shadow. You can correct the photo by turning the slider shadow move to the right to lighten the dark areas and reveal more details. You can use the regulator shadow together with the controls Highlights and Midtones use to compensate for the lighting.
Midtones: Adjusts the brightness in the middle tonal ranges of an image. After adjusting the highlights and shadows, you can adjust the image with the slider Midtones fine tune.

The regulator Highlights and shadow can lighten or darken certain areas of an image.

Use histogram

You can use the histogram function to display the tonal range of images and thus determine whether and how the color and tone of the image should be adjusted. For more information on the histogram, see Using histograms.

Display images in the image adjustment editor

The tools in the Image Adjustment Editor allow you to view images in a variety of ways so that you can assess the color and tone adjustments you have made. You can rotate images, pan to a new area of ​​the image, enlarge or reduce the image, and choose how the corrected image should be displayed in the preview window.

Use other adjustment filters

Although you can use the Image Adjustment Editor to adjust color and tone, a special adjustment filter is occasionally required. You can use the powerful adjustment filters in Corel PHOTO-PAINT to make precise adjustments to images. For example, you can adjust images using a histogram or tone curve. For more information about adjustment filters, see Using individual color adjustment effects and tools.


Move the slider temperatureto make the colors warmer or colder, then use the slider to adjust the color correction tint even better.
Move the slider saturation to the right to increase the color intensity in the image or to the left to decrease the color intensity.
Move the slider brightness right to lighten the image or left to darken the image.
Move the slider contrast right to make the light areas lighter and the dark areas darker.
Move the slider Highlightsto make the lightest areas of the image lighter or darker. Then move the slider shadowto make the darkest areas of the image lighter or darker. Then move the slider Midtonesto fine-tune the middle tonal ranges in the image.
