The Halftone filter simulates the look of continuous tone through a choice of screen types.
This filter can be applied as a non-destructive, live filter. It can be accessed via the Layer menu, from the New Live Filter Layer category.
Settings
The following settings can be adjusted in the filter dialog:
Screen—provides a choice of how the continuous tone is generated from Monochrome, Colour, Line or Circular.
Dot—determines the operator used to generate the dot tone. Choose from Cosine (smooth) or Round (sharp). Only applicable when Screen is set to Monochrome or Colour.
Cell Size—dictates the size of each individual dot, line or circle that makes up the continuous tone.
Contrast—increases or decreases the tonal contrast between each cell.
Grey Component Replacement—(Colour screen type only) controls the contrast of areas between colour cells.
Under Colour Removal—(Colour screen type only) controls the influence of the colour cells. Increase to lessen their influence and desaturate the image.
