|Sometimes you may want to change the proportions of a subject to create a special effect. Making random changes isn't nearly as effective as changing the proportions on a grid, because the distorted elements still have correct relationships. Make a grid of same-size squares on your original. Then on a support that is the size of your final drawing, make a grid changing the spacing of the vertical and horizontal lines, as shown in the sketches. Transfer your lines from the squared-off grid to the distorted grid one space at a time, recording the elements found in each space to fit the correspondidng space. The result will be an altered appearance of the subject, whether a portrait, head or still life. Try this for yourself on different subjects.
For more examples of distortion see The New Creative Artist. pp. 73. Also see my caricature by Susan Moreno.
