This month I am doing the Exploring Patterns (Chapter 6) exercises in Keys to Drawing with Imagination by Bert Dodson. This drawing is my solution to Exercise 34, Shape Mergers. The exercise is to take a news photo and draw it in black, white, and two shades of gray. Shapes with similar shades are merged, and the viewer's eye fills in the details.
I used a photo of a group of Fort Worth school children who are waiting for JFK's motorcade. You can see the photo here.
