USING PHOTOSHOP ELEMENTS 8
Color and tonal correction

You can do any of the following with the Levels dialog box:

•

Set the shadow and highlight values to make sure that your image uses the full tonal range.

•

Adjust the brightness of the image’s middle tones without affecting the shadow and highlight values.

•

Fix a color cast by making grays neutral. You can also enhance an image by adding a slight color cast, for example, 
by adding a warming effect on a sunset.

•

Target shadow and highlight RGB values if you are preparing images for commercial printing.

When you work with Levels, you can work directly on the image pixels or through an adjustment layer. Adjustment 
layers give you flexibility in the following ways:

•

You can modify an adjustment at any time by double-clicking the adjustment layer to reopen the Levels dialog box. 

•

You can reduce the effect of an adjustment by lowering the adjustment layer’s opacity in the Layers panel. 

•

You can stack adjustment layers to make multiple adjustments without degrading the image because of too many 
successive adjustments.

•

You can use the adjustment layer’s layer mask to confine an adjustment to a portion of your image.
