Halftone
Edit workspace
The Halftone effect applies a series of dots to the image, rather than a
continuous tone. Halftone images can be printed easily and are
therefore typically used in newspapers and magazines. You can choose
different sizes, colors, and shapes for the Halftone effect. Larger dots
produce darker, more dense areas of the image, whereas smaller dots
produce lighter areas. You can access the Halftone dialog box by
choosing Effects Artistic Effects Halftone.
The Halftone dialog box contains the following controls:
• Halftone pattern — lets you choose a line, round, or square
pattern
• Size — lets you choose a size for the pattern cell
• Screen angles — lets you choose the angles for the screen. In the
case of a grayscale image, you can choose only one angle. For an
RGB image, you can choose an angle for each color channel.
• Use as overlay — lets you adjust the strength of the effect and
apply blending
• Blend mode — lets you choose from a wide variety of blending
effects
• Opacity — controls the strength of the effect. As the opacity
increases, the image displays more of the effect and less of its
original appearance.
