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).
Adjusting the Contrast Layers
Now that we have the contrast layers created, the rest is very simple. Simply follow these steps to achieve your desired effect.
Step 8
Change the blending mode of the layers to the following:
- For a high contrast effect: Top Layer: Screen
Middle Layer: Multiply - For a low contrast effect: Top Layer: Multiply
Middle Layer: Screen
Step 9
To
reduce the strength of the effect, select the top two contrast layers
and group the selected layers (Layer> Group or Ctrl+G). Then, select
the new group and adjust the opacity.
