Chiaroscuro (Italian for “light-dark”) pushes an extreme range between light and shadow, with very little gentle mid-tone gradation, to make forms feel sculptural and dramatic.
It's the technique behind Caravaggio and Rembrandt's most famous work — a single controlled light source and deep, decisive shadow can make even a simple subject feel monumental.
Decide its direction and keep it consistent across the whole piece.
Lay down just light, midtone, and dark shapes first — resist blending until the big shapes are right.
True chiaroscuro darks are much deeper than a beginner’s instinct — don’t be afraid of pure black.
Every object throws a shadow with a hard edge nearest itself, softening as it moves away.
Save the lightest value for only one or two focal points so it stays the eye’s focus.
Save smooth blending for curved surfaces; keep hard edges wherever a surface changes direction sharply.
Light a simple object (an apple, a mug) with a single desk lamp in an otherwise dark room and draw only what you see — no imagined detail in the shadow side.
