Automatically Remove Colorcasts from Images
you can usually do a pretty good job of correcting the color with one of the many Photoshop Elements 10 adjustments. Sometimes, an unexpected colorcast (a shift in color) can be avoided at the shooting stage, for example, by using (or not using, in some cases) a flash or lens filter or by setting the camera’s white balance for lighting conditions that aren’t present.
If you ever took a photo in an office or classroom and got a funky green tinge in your image, it was probably the result of the overhead fluorescent lighting. To eliminate this green colorcast, you can apply the Remove Color Cast command in Photoshop Elements 10. This feature is designed to adjust the image’s overall color and remove the cast.
Follow these short steps to correct your image:
In either Full Photo Edit or Quick Photo Edit mode, choose Enhance→Adjust Color→Remove Color Cast.
The Remove Color Cast dialog box appears. Move the dialog box to better view your image.
Click an area in your photo that should be white, black, or neutral gray, as shown.
The colors in the image are adjusted according to the color you choose. Which color should you choose? The answer depends on the subject matter of your image. Feel free to experiment. Your adjustment is merely a preview at this point and isn’t applied until you click OK. If you goof up, click the Reset button, and your image reverts to its unadjusted state.
If you’re satisfied with the adjustment, click OK to accept it and close the dialog box.
If the Remove Color Cast command doesn’t cut it, try using the Color Variations commands or applying a photo filter. For example, if your photo has too much green, try applying a magenta filter.
