Lost and Found Edges

In order to add a dramatic effect to a drawing, use the concept of lost and found edges. A lost edge occurs where the edge of the form seems to disappear into the background. You lose light edges in a light space or dark edges in a dark area. Basically, a lost edge fades into an area with a similar value, while a found edge relies upon contrasting values to define it.

One strong light source and a dark background will provide ample opportunities for dramatic effects. Keep your use of contour line to a minimum. Use it only in discrete places as a very subtle accent. Most of the form should be defined by the edges created by the transitions between light to shadow. Add some limited details and softer descriptive values within the light side of the form.

Use Lost and Found Edges to Create a Dramatic Effect

The contrast of strong black and white creates drama as this figure almost emerges from the deep shadows of the background. I used midtones and lights to clarify the details.
