Step 2: Increase contrast
First, we’ll increase the contrast as we usually would. There are many ways to increase contrast but we’ll show you how to do it using Curves. Choose Layer > New Adjustment Layer > Curves. In the Curves tool, create a slight S curve like the image below.

Step 3: Create a new 50% gray layer
Now we’ll create the mask for the Curves adjustment layer. The mask will specify how visible the Curves adjustment layer is according to the brightness of the area. To do this, we first need to create a layer with a 50% gray fill. Create a new layer then choose Edit > Fill.

Step 4: Create a custom selection using Calculations
With the 50% gray layer created, we will use the calculations tool to create the mask that will be used for the Curves adjustment layer. Choose Image > Calculations and enter in the settings below. This will create a selection around the highlights and shadows of the image.
