Lock Transparent Pixels Lock Image Pixels Lock Position Lock All Blending modes Blending modes create amazing special effects by changing the way layers affect each other. At the beginning of this chapter I asked you to imagine that layers were like transparencies stacked on top of one another.

Imagine that your transparencies are made of gel rather than plastic and that rather than sitting on top of one another they can blend with each other. Then imagine that you can determine which areas of the images on your transparencies would blend and how. Last but not least imagine that you finish blending them and you hate the result but you find that you can pull them apart and start all over with your original images. But blending modes do more than blend two images together. They can be used on any layer that is added to your Layers panel. You can use them to change the way a layer style is applied to blend a pattern into an image or even to change an adjustment layer into a special effect. The drop-down menu at the top of the Layers panel shown in Figure shows the different blending modes you can use to choose how the selected layer affects the layers under it.

If you choose the Dissolve blending mode it looks .
