Choosing a Medium Under a Deadline
A student has 90 minutes in a supervised exam to produce one sustained observational study of a crumpled fabric still life lit by a single hard lamp. Available media: soft graphite, compressed charcoal, fine-liner pen, and watercolour. The marking criteria reward strong tonal range (at least five distinct values), accurate proportion, and evidence of mark-making control. The student is most comfortable with fine-liner pen but worries it cannot show tone quickly. The fabric has deep folds and a bright highlight on one ridge.
1. Compare the four media against the criteria and recommend a choice, justifying it with the demands of the subject and the time limit.

Compressed charcoal best matches all three criteria within 90 minutes. It delivers the widest tonal range fastest: it can go from near-black in the deep folds to a lifted highlight on the ridge (by erasing or leaving paper), easily reaching five or more values. It also produces varied marks - smudged masses for shadow, sharp edges for fold creases - which demonstrates mark-making control. Proportion can be blocked in broadly before refining.
Soft graphite gives good value range but slower, and its shine limits deep darks. Fine-liner pen gives precise, controlled marks and suits the student's comfort, but building five values by hatching is slow and risks running out of time; it also struggles with the soft transitions of fabric. Watercolour could show luminous tone but demands drying time and is unforgiving of proportion errors in a timed exam. Recommendation: charcoal, with the pen reserved for a few crisp accent lines if time allows.
2. The student insists on the fine-liner. Describe a strategy that could still meet the tonal criterion, and state the main risk.

Strategy: use cross-hatching and stippling to build value in layers. Establish the five values by varying hatch density and direction: sparse single-direction hatching for the lightest mid-tone, crossed hatching for the next, dense multi-directional hatching for dark, and near-solid fill or tight stippling for the deepest folds. Reserve blank paper for the bright highlight ridge, since pen cannot be lifted. Work from light to dark so errors are harder to make, and map the value zones lightly in pencil first to protect proportion.
Main risk: time. Hatching five values across a full still life is slow, and dense areas can look mechanical rather than controlled, which may cost marks on mark-making quality. A secondary risk is that the drawing reads as flat line rather than form if hatch direction ignores the folds. Mitigation: block proportions in the first 20 minutes, commit to four large value zones rather than fussing, and accept a slightly simplified tonal plan to finish with control intact.
