If you edit beyond the basics and haven’t discovered Selective Color Correction, it’s worth taking a look.
Change only one color
Selective Color allows you to change the amount of process colors in the primary colors in a digital image. A color can be selectively be enhanced, even changed, without affecting other primary colors.
For example, Selective Color Correction can be used to decrease the amount of cyan in blue areas in a photo, all without changing the amount of cyan in green areas. Color changes in an image can be dramatic, but more often than not Selective Color Correction is used to achieve more subtle changes.
In the first photo accompanying this article, much of the grass in the lower foreground area was brown. With Selective Color, it was possible to make much of it appear greener.
Portions of the brown grass were selected with the Selection tool so as not to alter neutral colors throughout the image. Only the selected areas were affected by changes.
You don’t have to make selections. But if you don’t and a color exists in may areas, the entire look of an image can change.
Picking and changing a color
Neutral was picked from the drop down menu. Cyan, Magenta, Yellow and Black colors were increased or decreased via the sliders as shown in the illustration. The result: selected areas of the brown grass became greener.
There is no right or wrong about what percentages of each color to change. What’s important is to experiment until the selected area color looks the way you want it.
Layer or Adjustment Layer?
In programs such as Photoshop and Photoshop Elements, you can make a Selective Color Correction on an individual layer (Choose Image > Adjustments > Selective Color). A separate Adjustment Layer can also be used (Choose Layer > New Adjustment Layer > Selective Color).
The value of using an Adjustment Layer is that you can apply a variety of color and tonal changes without altering the original image. Any tweaks are stored in the separate adjustment layer.
When using an Adjustment Layer, any changes affect all the layers just below it. If you don’t like the results, click open the Adjustment Layer and make additional adjustments to the layer. Or, simply delete it. The original image remains in tact.
Using the Selective Color Correction has many applications such as brightening certain colors in a photo, or removing a color cast from an image. It’s not appropriate for every image but, when used correctly, images can be positively enhanced.
