About 35 years ago, when I was in art school, my buddies and I would take turns posing for each other in one minute costumed poses.
In the series at the upper left I tried to capture the basic gesture of the folds of the costume using pencil and white gouache. At upper right is more of a tubular form emphasis, using just light and shadow and no outline.
In the middle row, I used a brush and ink to try to capture the black silhouette. In the bottom row, we moved the light around to the back and I tried drawing edge-lit silhouettes, where the light side becomes the paper color.
Drawing directly with the brush, I first drew the side away from the light before sorting out the complex lit side. This way of sketching gives a very photographic effect.
