Adjusting the color and tone of RAW camera files
You can adjust the color and tone of an image by using the following settings.
Color depth
Color depth refers to the number of colors an image can contain. One of the advantages of using RAW camera files is that they can contain
more colors than photos saved as JPEG or TIFF files. This greater number of colors makes it easier to reproduce colors accurately, reveal detail
in shadows, and adjust brightness levels.
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.
White balance
White balance is the process of removing unnatural color casts from images so that image colors appear as they do in real life. White
balance takes into consideration the lighting conditions in which a photo was taken and sets the color balance to produce realistic image
colors.
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.
Tonal adjustments
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.
