It's under Photoshop Effects, Pixelate > Colour Halftone. I'm afraid I don't know the German translation.
Hi Doug A Roberts,
thanks for the quick reply. I saw that in those tutorials, but in my illustrtator I do not have this categorie under effects. It's like the screenshot shows, Pixelate (in German the same) does not appear in that effect-list.
How come that it's not there?
