  abstract = {This contribution introduces the basic techniques for digital
              facial engraving, which imitates traditional copperplate
              engraving. Inspired by traditional techniques, we first establish
              a set of basic rules thanks to which separate engraving layers are
              built on the top of the original photo. Separate layers are merged
              according to simple merging rules and according to range
              shift/scale masks specially introduced for this purpose. We
              illustrate the introduced technique by a set of black/white and
              color engravings, showing different features such as
              engraving-specific image enhancements, mixing different regular
              engraving lines with mezzotint, irregular perturbations of
              engraving lines etc. We introduce the notion of engraving style
              which comprises a set of separate engraving layers together with a
              set of associated range shift/scale masks. The engraving style
              helps to port the look and feel of one engraving to another. Once
              different libraries of pre-defined mappable engraving styles and
              an appropriate user interface are added to the basic system,
              producing a decent gravure starting from a simple digital photo
              will be a matter of seconds. The engraving technique described in
              this contribution opens new perspectives for digital art, adding
              unprecedented power and precision to the engraver’s work.},
