Find a family photo from your childhood to use as a reference image. Or you might take a photo of a familiar place that has meaning for you. You could photograph the hallways or classrooms at your school, the buildings in your town, or your home. Select or take a photo that emphasizes the light in the scene. Then, in your sketchbook, draw the major forms in the photo. Simplify the scene in your sketch, leaving out the small details. Take note of where the light source is located. Focus on capturing the highlights and shadows, which can each be represented with shape. When you are satisfied with your composition, sketch it on your canvas board.
Tip: Treat the forms in your sketch like geometric shapes.
