What this dot point is asking

SEAB wants you to apply tonal shading techniques in your drawing: the practical methods of putting tone onto paper and controlling the full range from light to dark. You should know hatching, cross-hatching, blending and stippling, understand how to build a complete tonal range, and know how graphite, charcoal and pen behave. This builds directly on the understanding of tone as an element, turning the theory of light and shadow into something your hand can actually produce. The central insight is that there are several distinct ways to make tone, each with its own character, and that committing to the full range from clean lights to rich darks is what gives a drawing depth and convincing form.

The answer

The main shading techniques

There are several distinct ways to build tone, and the rule across all of them is that denser marks read as darker. Hatching uses a series of roughly parallel lines; the closer together they are, the darker the area appears, giving a controlled, linear, slightly sketchy tone. Cross-hatching layers a second (and third) set of lines across the first at an angle, building up darker, richer tone and a structured surface, ideal for deep shadows. Blending smudges or rubs the marks together (with a finger, paper stump or cloth) into smooth, gradual tone, suiting soft surfaces and rounded forms. Stippling builds tone from many small dots, denser dots reading as darker, giving a precise, textured effect that works especially well in pen.

Building a full tonal range

A strong drawing uses the full range from the brightest highlight to the darkest shadow. The brightest tone is often simply the untouched white of the paper, so highlights are reserved by leaving the paper bare rather than added later. Tone is built by controlling pressure and layering: light pressure or sparse marks give pale tones, while heavier pressure or denser, layered marks give the darks. A useful habit is to make a tonal strip first, a row of patches from white to black, to train your control of the whole range before applying it.

How the media behave

Each drawing medium produces tone differently. Graphite pencils come in grades from hard (H, giving pale, fine, controllable tone) to soft (B, giving darker, richer tone), so a range of grades covers the whole scale; graphite is clean and precise but its darkest dark is limited. Charcoal is soft, dark and expressive, reaching deep velvety blacks and broad tones quickly, ideal for dramatic, large or loose work, though it smudges easily. Pen and ink give crisp, permanent marks with no tonal blending, so tone must be built entirely through hatching, cross-hatching or stippling, which makes it excellent for disciplined linear shading.

Rendering smooth gradation to model form

To make a flat shape look like solid form, the tone must change gradually and smoothly across it, with no abrupt steps. Whichever technique you use, the gradation from highlight through mid-tones to core shadow should be controlled so the surface looks rounded. Smooth gradation, plus a reserved highlight and a committed dark, is what turns shading from flat grey into convincing three-dimensional form.

Examples in context

Example 1. A pen-and-ink illustration. A detailed pen illustration shows tone built entirely from line: areas of close hatching and cross-hatching read as shadow, sparser lines as mid-tones, and untouched paper as light, with no blending at all. It demonstrates how a full convincing tonal range can be created from nothing but the density of marks.

Example 2. A charcoal portrait. A charcoal portrait exploits the medium's reach into deep, velvety darks and broad soft tones, blended to model the rounded forms of the face while the bare paper holds the highlights. It shows how the choice of medium shapes the look of the shading, charcoal giving drama and softness that a hard pencil could not match.

Try this

Q1. Explain the difference between hatching and stippling. [2 marks]

  • Cue. Hatching builds tone with sets of parallel lines, darker where they are closer together; stippling builds tone with many small dots, darker where the dots are denser.

Q2. Why is it important to use the full tonal range in a drawing? [3 marks]

  • Cue. Using the full range from clean light highlights to rich darks gives a drawing depth, drama and convincing solid form, whereas staying in a narrow band of mid-greys makes it look flat and weak.

Q3. Contrast how graphite, charcoal and pen produce tone. [3 marks]

  • Cue. Graphite gives fine, controllable tone across pencil grades but a limited darkest dark; charcoal gives deep, soft, expressive darks and broad tone but smudges; pen gives crisp permanent marks with no blending, so tone is built only through hatching or stippling.

Original6 marksDescribe four different shading techniques and explain the kind of surface or effect each one suits. Use your own examples.
Show worked answer →

Take four distinct techniques. Hatching is a series of roughly parallel lines, with closer lines reading as darker; it suits a controlled, sketchy build-up of tone and works well with pen or pencil. Cross-hatching layers a second set of lines across the first, building darker, richer tone and suiting deep shadows and a structured look. Blending smudges or rubs the marks into smooth, gradual tone, suiting soft surfaces such as skin or rounded forms. Stippling builds tone from many small dots, with denser dots reading as darker, suiting fine, textured or precise effects and working well in pen.

Tie each to a use: hatching and cross-hatching for structured, linear work; blending for smooth rounded form; stippling for texture and control.

What markers reward: four genuinely different techniques described accurately, the darker-where-denser principle, and a sensible surface or effect for each.

Original5 marksExplain how to build a full tonal range in a drawing, and why using the full range from light to dark improves the work. Refer to the medium you would use.
Show worked answer →

Set out that a full tonal range runs from the brightest highlight (often the untouched white of the paper) through mid-tones to the darkest shadow. Describe building it by controlling pressure and layering: light pressure or sparse marks for pale tones, heavier pressure or denser layered marks for darks, leaving the paper white for highlights. Mention a medium such as graphite using a range of pencil grades, or charcoal for deep rich darks.

Explain why it matters: using the full range gives a drawing depth, drama and convincing form, while a drawing stuck in a narrow band of greys looks flat and weak. Committing to real darks and clean lights is what makes a drawing read powerfully.

What markers reward: the highlight-to-shadow range, the method of building tone through pressure and layering (reserving the paper white), the chosen medium, and the point that the full range gives depth and avoids flatness.
