Adobe Photoshop CS6 Top 100 Simplified Tips and Tricks by Lynette Kent

REMOVE A COLORCAST to improve the overall color
Whether you have a scanned image or one from a
digital camera, your image may show a colorcast due
to improper lighting, white balance settings, or other
factors. A colorcast often appears as a reddish, bluish,
or greenish tint over the whole image. Photoshop has
many tools that you can use to remove a colorcast,
including the White Balance setting in Camera Raw,
and sometimes you may need to try different ones,
depending on the photograph. Using the Match Color
command as shown here to remove a colorcast is
simple and often works well.
Intended for matching the colors between two
images, the Match Color command uses advanced
algorithms to adjust the brightness, color saturation,
and color balance in an image. Because you can
adjust the controls in different combinations, using
this command on just one image gives you better
control over the color and luminance of the image
than many other tools.
Using the Match Color command on a duplicated
layer, you can protect the original image as you
compare the adjustment and also adjust the layer’s
Opacity slider. Blend the results with the Background
layer to achieve the best color for your image.
