Contrast LayersReviewed by Denny Tang on Sep 11Rating:
Preparing the Document
In this page, we’ll create the two contrast adjustment layers. One will be for the highlights of the image and the other for the shadows.
Step 1
Open a photo you would like to edit. Or, you may use the
photo used in this tutorial (from iStockPhoto).

Step 2
Duplicate the layer (Layer> Duplicate Layer or Ctrl+J) and add a layer mask to the new layer (Layer> Add Layer Mask> Reveal All).

Step 3
Make sure the layer mask is activated. The thumbnail of the layer mask in the layers window should have a white border around it. If it doesn’t, click on the thumbnail to activate the layer mask.
Step 4
With the layer mask selected, open the Apply Image tool (Image> Apply Image). The default settings should be fine so you may simply click OK if the settings are default:
Layer: Merged
Channel: RGB
Invert: Unchecked
Blending: Multiply
Opacity: 100%

Step 5
Duplicate the current layer (Layer> Duplicate Layer or Ctrl+J).

Step 6
Activate the layer mask of the top layer. Make sure the layer mask is activated. The thumbnail of the layer mask in the layers window should have a white border around it. If it doesn’t, click on the thumbnail to activate the layer mask.
Step 7
With the layer mask activated, Invert (Image> Adjustments> Invert or Ctrl+I).
