One of our students, doing a wonderful job of depicting drapery in two dimensions.
GOAL: Do an observational drawing or painting of fabric. Pay close attention to the variations of gradation. There are some areas of strong contrast and other areas of subtle contrast. Depending on how you set up the lighting and arrange the fabric, some edges may be very soft (subtle) and others may be very sharp.
Our OBSERVE lessons in our Curriculum are meant to build skills of observation. Students learn to edit the information in front of them in order to include only the elements necessary for a successful composition.
