- Open an image
- Click on the 'Create adjustment layer' icon in the Layers palette (looks like a half white/half black circle) and select the type of adjustment layer you want to apply. For this example, let's select the 'Hue/Saturation' adjustment layer.
- In the Hue/Saturation dialog click on the 'Colorize' checkbox and move the sliders until you get a result you like (I did Hue:50, Saturation:50, Lightness:-20) and click OK
- Select the Cookie Cutter tool (looks like a heart icon with a little person inside) and select your desired shape in the options bar (by default the shape is a heart).
- Click and drag your shape on the Hue/Saturation adjustment layer you just applied.
- Adjust the position, scale, and rotation and then apply your Cookie Cutter crop by double-clicking within the shape you created or click on the check icon in the options bar.
- There you go. You've used the Cookie Cutter tool to create a mask on your adjustment layer!
- If you want to play further, try applying some Layer Styles (See Styles and Effects palette) to your adjustment layer. WOW!
