Students are to create value scales using at least 5 different charcoal materials, masking each strip with tape and labeling the material used. The gradations should be smooth without blemishes, allowing more room for light grays and avoiding sudden fading. Practicing different value spectrums will help students achieve subtle tonal gradations and a convincing command of basic drawings. The objectives are smooth value shifts with even transitions, overall attention to detail, and demonstrated grasp of materials.
