| • | To adjust the color and tone of a RAW camera file |
You can adjust the color and tone of an image by using the following settings.
The Camera RAW Lab lets you process the RAW camera files as 48-bit or 24-bit images. 48-bit images offer more accurate color representation and prevent loss of image quality during retouching. Note that some of the special effects available in CorelDRAW cannot be applied to 48-bit images.
By default, when a RAW camera file is brought into CorelDRAW, it reflects the camera setting for white balance. This setting appears as the preset As shot in the White balance list box. If you are not satisfied with this setting, you can have the white balance adjusted automatically by choosing the preset Auto. You can also apply any of the following presets: Daylight, Cloudy, Shade, Tungsten, Fluorescent, or Flash. These presets let you simulate different lighting conditions.
In addition, you can use the Eyedropper tool to automatically adjust the contrast in an image according to the white or gray point that you sample in the preview window.
If the White balance options do not produce the results you want, you can use the following controls to remove color casts:
| • | Temperature slider — lets you correct color casts by adjusting the color temperature of an image to compensate for the lighting conditions at the time the photo was taken. For example, to correct a yellow color cast caused by taking a photo indoors in dim incandescent lighting, you can move the slider to the left. Conversely, to correct a blue color cast caused by intense lighting conditions, you can move the slider to the right. |
| • | Tint slider — lets you correct color casts by adjusting the green or magenta in an image. You can add green by moving the slider to the right; you can add magenta by moving the slider to the left. Moving the Tint slider after using the Temperature slider lets you fine-tune an image. |
You can use the following controls to adjust the tone of RAW camera files.
| • | Saturation slider — lets you adjust the vividness of colors. For example, by moving the slider to the right, you can increase the vividness of a blue sky in an image. By moving the slider to the left, you can reduce the vividness of colors. |
| • | Exposure slider — lets you compensate for the lighting conditions at the time the photo was taken. Exposure is the amount of light allowed to fall on the image sensor of a digital camera. High exposure values result in areas that are completely white (no detail); low values result in increased shadows. Exposure values (EV) range from -3.0 to + 3.0. |
| • | Brightness slider — lets you brighten or darken an entire image. If you want to darken only the darkest areas of an image, you must use the Shadow slider. |
| • | Shadow slider — lets you adjust the brightness in the darkest areas of an image without affecting the lighter areas. For example, a bright light behind a photo subject (backlighting) at the time a photo is taken can cause the subject to appear in shadow. You can correct the photo by moving the Shadow slider to the right to lighten dark areas and reveal more detail. |
