When applying a Halftone dither, we are able to vary the screen type, angle for the halftone, lines per unit, and the unit of measure. A Halftone dither tricks the eye into seeing different shades of gray by varying the pattern and density of black and white pixels in a photo. When engraving a photograph on wood, a Halftone dither works best. There are different types of dithering patterns applied to black and white photos: Halftone, Line Art, Ordered, Jarvis, Stucki, Floyd-Steinberg, and Cardinality-Distribution.
