Contour hatching is an artistic shading technique where lines follow the natural curves of a subject, rather than being simply parallel.
Understanding Contour Hatching
In drawing and illustration, hatching is a method of creating tonal or shading effects by drawing sets of parallel lines. Contour hatching takes this technique a step further. Instead of using straight, parallel lines, the hatch marks follow the contours of the subject. This means the lines curve and flow along the form of the object you are drawing.
How it Differs from Basic Hatching
Basic hatching typically uses parallel lines to create areas of value (light and shadow). While effective for shading, it doesn't necessarily convey the form of the subject. Contour hatching actively describes the shape and structure of the form through the direction of the lines.
As stated in the reference, "Rather than simple parallel lines, contour hatching is when the lines follow the contours of the subject."
Benefits of Using Contour Hatching
Using lines that follow the curves of a subject offers significant advantages:
- Enhances Volume and Three-Dimensionality: By aligning with the form, the lines make the object appear more solid and round, greatly enhancing the sense of volume and three-dimensionality.
- Provides Value: Like other hatching methods, it effectively builds up tonal values to depict light and shadow.
- Describes Form: The direction of the lines directly communicates the shape and curves of the subject.
The reference notes that this method "greatly enhances the sense of volume and three-dimensionality of anything you are drawing, in addition to providing value."
Practical Application
Consider drawing a curved surface like a sphere or a hand. With contour hatching, you would draw curved lines that wrap around the form, mimicking its shape. The reference provides an example: "Here, the hatch marks follow the curves of the hand." This demonstrates how the technique is applied to depict organic or rounded forms realistically.
By adjusting the density and direction of these curved lines, artists can create rich textures and values while simultaneously defining the contours of their subject.
