Layers

Layers are, without a doubt, the single most important aspect of Photoshop. Nothing worth doing in Photoshop can or should be done without the use of layers.

I have an example to show how layers work.

1. First, I open my picture from my desktop.

2. The picture will automatically become Background Layer. This is first layer.

3. Then, I create a new layer. This is second layer.

4. Use Text Tool to text words "Nemo Fish". It will under to the new layer.

5. In the Background Layer, right click to click Duplicate layer. It will copy a layer to another layer. This is third layer.

6. Select the Quick Selection Tool to select the picture without select the nemo fish.

7. So, now go up to the Filter menu, choose Blur, and then choose Gaussian Blur.

8. The background of the nemo fish become blur. This is all for the third layer.

Finally, my nemo fish is done.
