Drawing and Observation from Primary Sources
Why primary sources matter
Examiners reward evidence that you looked at a real object, person or place rather than inventing from memory or copying a photograph. A primary source is the thing itself: a shell on the table, a seated model, a building you visited. Secondary sources (photos, other artists' drawings) may support your work but should not replace direct observation.
Core concepts to master
- Proportion and comparative measurement: judge height against width, use a pencil held at arm's length, and check angles against vertical and horizontal references.
- Contour and gesture: a contour line describes an edge and the form turning away; a gesture line captures movement and weight quickly.
- Structure before surface: block in simple volumes (cylinder, cube, sphere) before adding texture.
- Light logic: identify one light source, then separate highlight, mid-tone, core shadow, reflected light and cast shadow.
- Foreshortening and ellipses: circles seen at an angle become ellipses; limbs pointing towards you shorten.
Traps in questions
- Drawing every outline with the same weight, so the drawing looks flat and diagrammatic.
- Shading with smudged grey instead of locating a consistent light direction.
- Copying surface decoration (patterns, lettering) before the underlying shape is correct.
- Confusing a study (focused investigation of one aspect) with a finished composition.
- Claiming a source is primary when it is a photograph or a screen image.
Worked example: the three-check rule
Before adding tone, check the drawing three ways: (1) hold it at arm's length and compare the widest width with the tallest height; (2) sight the main diagonal of the subject and compare it with the same diagonal on the page; (3) find the negative spaces between forms and ask whether they match. If any check fails, correct the structure first. Only then apply tone, keeping the lightest area untouched paper and the darkest mark in the core shadow.
Rule of thumb
Spend roughly a third of your time on measurement and structure, a third on tone, and a third on refinement and selective detail.
