Use a Value Ladder, Not a Smudge

Three tones can describe a form.

The small question

Three tones can describe a form. This exercise asks you to check a visible relation rather than judge whether the whole sketch is good.

Try it in front of the subject

On scrap paper make light, middle and dark pencil patches. Apply them to a folded cloth: paper white for a highlight, middle tone for the broad fold and dark only in the deepest crease. Keep the first marks light enough that you can revise them after another look.

What this exercise cannot prove

A photograph or changing lamp can flatten or exaggerate tones. If drawing from life, keep the light source stable for this exercise and acknowledge any change. An example can suggest where to look, but the scene in front of you is the evidence for your drawing.

A second pass

Squint at the cloth and ask whether the three largest tonal regions still read from a distance. Keep the first attempt beside the revision so you can see which choice changed.

A field-note challenge

Hold the three-tone study at arm’s length. If every fold seems equally dark, reserve the darkest patch for one deepest crease and lift other marks with an eraser. Then compare the original cloth: its brightest area may be smaller than the untouched white on your page.
