Use negative space to check placement
See this course’s project requirements
A pencil or digital three-object still life with measured proportions, negative-space checks, a five-value scale and a before/after correction.
Keep your working files in your own notebook or software. Save a private description, checklist, and work link in My Proof.
What to include
- Produce a three-object block-in and final line/value drawing.
- Record a reference unit and at least two proportion comparisons.
- Check negative spaces with identified edges.
- Include five distinguishable values and a stated light direction.
- Show one before/after correction and an intentional-style note if needed.
Review and revise
Use these criteria to check your work and choose what to improve.
- Observation: large shapes and relative dimensions follow the chosen reference.
- Placement: identified gaps/overlaps are coherent.
- Value: marks support the stated light/form model.
- Revision: one specific correction has independent evidence.

The idea in everyday life
Negative space is the visible area around/between forms. It offers a second comparison route when an object outline looks convincing but sits in the wrong place. Check the front rectangles separately from the box’s receding top, which may extend into a gap. Label which edges you compare instead of claiming every visible gap is identical.
The shape between objects can check the shapes themselves.
Use negative space to check placement — worked practice
The shape between objects can check the shapes themselves.
Cup front runs x50–130; box front runs x170–270; ball bounding box runs x310–380. The front-bounds gaps are 40 each. In a half-scale sketch they become 20 units. The box’s top extends to x290, so the gap from that top edge to the ball’s left bound is 20, not 40. Keeping these comparisons separate prevents a false “all gaps equal” conclusion.
1. 3.1 Use
Outline the two spaces between the three front bounding boxes without adding object detail. Write each pair of x-edges used in the gap calculation.
You should see: The compared front edges are identified.
2. 3.2 Use
Calculate 170−130 and 310−270. Compare the equal front gaps with your actual drawing.
You should see: Both original front gaps are 40 units.
3. 3.3 Use
Now trace the box top reaching x290. Calculate the smaller top-to-ball gap and mark why it differs from the front gap.
You should see: Top-edge gap is 20 units and labeled separately.
4. 3.4 Use
Move the box front 20 units right in a copied plan while retaining the cup and ball. Recompute both front gaps and correct placement accordingly.
You should see: After moving the box right, front gaps are 60 and 20.
What to finish
A negative-space overlay and changed-placement check.
Watch for this
Comparing a receding top edge with a front edge while assuming the gap measures the same relationship.
How can I tell I understand it?
You can locate a placement error using space rather than the object label.
