Start from the middle
- A toned ground 有色底 lets you draw both directions: darker with media, lighter with an eraser.
- Cover the paper with an even charcoal or graphite tone, or use grey/toned paper.
- The mid-tone start forces value decisions early — nothing hides behind white paper.
Additive or subtractive move?
Sort each studio move by its direction.
Subtractive drawing means using the eraser as a drawing tool.
Pulling light out of dark is drawing too.
The eraser is a pencil
- Subtractive drawing 减法素描 treats the eraser as a drawing tool — pulling light out of dark.
- Lift out 提白 the lights: dab a kneaded eraser 可塑橡皮 for soft light, drag for strokes, cut crisp lights with a hard eraser.
- Erasers make marks with character, just like pencils.
On a toned ground, the ground itself usually plays the role of the ____.
The ground is the ready-made middle value.
Pulling lights out of a toned surface with an eraser is called ____ out.
Lift out the lights.
Match the eraser move to its result.
Three subtractive marks.
Process as evidence
- On toned paper you add only darks and white highlights — the ground is the halftone.
- This process is visible experimentation 实验 with materials.
- Document a subtractive study in your journal: the CED loves process it can see.
Select all true statements about kneaded erasers.
They fill with graphite and must be kneaded clean.
A kneaded eraser fills with graphite and stops lifting — knead it clean often. And fix the final drawing lightly, or your carefully lifted lights will smear shut in the portfolio box.
Tone a page with willow charcoal, then draw a glass of water using only erasers: dab the soft window light, drag the streak down the glass, cut the sharp rim highlight. The drawing appears out of the dark.
A toned ground gives a ready middle value; subtractive drawing pulls lights out with erasers (lift out), so you draw in both directions — and the process itself is documentable experimentation.
