1. Create a new file with 900* 1000 pixels and a resolution of 72 pixels/inch. Set the foreground color, and everyone can choose their favorite color. As shown below, this case chooses blue, and Alt+Delete fills the foreground color blue.
2. Click the Lasso Tool in the toolbar to draw an irregular selection above the canvas, or press the Shift key or the "Add to Selection" button in the property bar to draw an irregular selection below the canvas.
3. Click the Q key to enter the quick mask, and click "Filter-Pixelization-Lattice" in turn, as shown below. Here, the cell size is set to 7, which determines the size of the edge bulge. Pull the slider to the right, and the bulge on the edge will become larger; pull the slider to the left, and the bulge on the edge will become smaller. In this case, it is set to 7, which is in line with the effect of tearing paper.
4. Press Q to exit the quick mask, create a new layer and set the foreground color. Light blue is chosen here, which is the same color system as the background color. Alt+Delete fills the foreground color, Ctrl+D cancels the selection;
5. In order to enrich the layering of the image, put two layers of torn paper and repeat the previous steps;
6. First, add a projection to the layer 1, select the layer 1, click the fx key under the layer panel, select "Projection" in the open menu, and observe the image changes while adjusting the parameters. When adjusting the angle, it is best to make the projection angle both upward and downward;
7. Hold down the Alt key and drag fx to the right of layer 1 to layer 2 and layer 3 to copy the projection effect to the other two layers.
8. Observing the image, you can see that the projection of the upper two layers is too large. You need to adjust the projection parameters of the upper two layers so that the projection of the upper two layers is slightly exposed. 1 and 2 floors are a little dark. Press Ctrl+M to bring up the curve panels, as shown in the figure below. Lift them up slightly to make the layers 1 and 2 light up respectively.
9. The paper surface has some graininess. Select Layer 3 and click Filter-Noise-Add Noise. In the Add Noise dialog box that opens, set the number to 3%. The bigger the number, the louder the noise and the rougher the paper.
10, at this point, the paper tearing effect is completed, and the text can be used as the background.
