Hatching and Cross-Hatching: How Artists Build Shadow with Lines

The classic line-based shading techniques and how to recognise their look in sketch and engraving-style photo effects.

Before smooth shading, artists used lines to show light and shadow. Hatching and cross-hatching remain among the most recognisable sketch techniques.

Hatching

Hatching uses sets of parallel lines to build tone.

  • Close lines make a darker area.
  • Wider spacing makes a lighter area.
  • The direction of the lines can follow the shape of the object, adding form.

Cross-hatching

Cross-hatching layers a second set of lines across the first, at an angle.

  • One layer gives a light tone.
  • Two layers make it darker.
  • Three or more layers produce deep shadow.

Where you'll see hatching

  • Pen-and-ink drawings and cartoons.
  • Old engravings and etchings, such as those by Albrecht Dürer.
  • Comics and graphic novels.
  • Newspaper illustrations from before photographs were common.

Hatching in photo effects

Some sketch effects imitate this look, turning shaded areas of a photo into fields of fine lines, and keeping bright areas clean. They work best on images with clear light and dark areas.

How to recognise a good result

  • Lines follow the forms rather than cutting across them randomly.
  • Highlights stay clear.
  • Dark areas have enough density to feel like shadow.
  • The mark size suits the size of the image.

Choosing photos

Photos with strong side lighting and clear shadow shapes produce the most convincing hatched looks: a portrait lit from a window, a building on a sunny day.

Try it yourself

Draw a simple sphere. Add light hatching on the side away from the light, then a second layer of crossing lines near the darkest edge. You'll see how form emerges.

A note on style

Hatching gives a graphic, textured feel, often more dramatic than smooth pencil shading. Try different effects on the same photo to compare.
