How do ps make posters to scale the material pictures? The following small series will give you a specific explanation. How to scale the material picture when ps makes posters? First find a poster, click on the picture layer, select Fill, and then select Filter-Blur-Gaussian Blur. Create a new mask in the pop-up layers panel. It is best to use a black mask (#). Add a bright color gradient to the mask background and adjust the hue. Specifically, you can adjust the bright colors in the layer style below, so that we can see light pink and dark gray. Then add some gray lines to the mask in black, so that the dark gray picture echoes the pre-existing gray picture, and at the same time add a gray rectangle to the black picture to form a bright background. This will form a very eye-catching effect, not very abrupt.
