Photoshop Filters: Using the Color Halftone filter
The first of our Pixelate filters, the Color Halftone filter, simulates the effect of a color halftone. So, there’s a simulation of the breakdown of the pixels into dots of cyan, magenta, yellow and black. That is, and this is the important point I want to make about this filter.Assuming that you convert the image to CMYK. And that’s an important point, because if you apply this filter to an RGB image, you get a half-tone pattern made up of dots that are red, green and blue.
