Make mosaic effect with Photoshop

In the example below we will create a mosaic image effect. When you first see this effect, it may be hard to imagine that it is just created by a filter, which is the filter so powerful? This is the halftone pattern filter.

① starts Photoshop CS and opens a picture that you want to work with, as shown in Figure 1. Then perform commands such as brightness/contrast, levels, and so on to enhance the sharpness of the image.
Figure 1
② set "foreground color" to black, "the background color is red, perform the filter → sketch → halftone pattern command, set size to 2 in the Halftone Pattern dialog box, contrast to 10, pattern type to line, and the effect is shown in Figure 2.
Figure 2
Note: In step 2, the size is set to 2 because the currently edited image format is relatively small, and if the edited picture is larger, the parameter needs to be increased, but the minimum must be set to 1.

③ the "filter → sketch → halftone pattern" command again. In the Halftone Pattern dialog box, set pattern type to point, others remain unchanged, and finally add some text to the image and add a stroke, drop shadow layer effect, as shown in Figure 3.
