PS Filter pixel how to use?

In the previous tutorial, when we introduced the basics of PS filters, we mentioned that PS contains 16 kinds of built-in filters. From today onwards, we will be combined with graphic cases to explain the PS each filter use method. The first to explain the PS filter is: Pixel, this is a what kind of filter, PS filter pixel How to use? Let's take a look at today's tutorial content!

PS Filter

First group: pixelate (Pixel)

The Pixelate (pixel) filter divides the image into a certain area, transforms the area into the corresponding color block, and then the color blocks form an image, similar to the effect of color composition.

1, Facet (color block filter)

Adjust parameters:

Maximum radius: Set the maximum radius of the halftone screen.

For grayscale images: Only channel 1 is used;

For RGB images: Use 1,2 and 3 channels, respectively, corresponding to red, green and blue channels;

Adjust parameters:

Cell Size: Resize the cell, do not set too large, otherwise the image will become unrecognizable, ranging from 3 to 300.
