At the Yarnell School of Fine Art, one of the most important skills any painter can learn is understanding light and shadow in painting. When artists learn to control values—the range from light to dark—they create depth, realism, and powerful visual impact.
Through value scales, tonal studies, chiaroscuro techniques, and underpainting techniques, artists can transform flat images into paintings full of atmosphere and dimension.
In this guide, we’ll explore how to master light and shadow and how value studies help artists plan successful paintings.
A value scale is a visual chart showing the full range of lightness and darkness in a painting—from pure white to pure black with multiple gray steps in between.
Understanding the value scale in painting is essential because values create:
Many artists create 10-step value scales as practice exercises to train their eyes to see subtle differences between light and dark areas. Below is an example of a 9-step scale. Occasionally, you will see 8-step scales also.
When painters understand values, they can:
Before focusing on color, professional artists often begin with tonal studies that map out values first.
The term comes from Italian and literally means “light-dark.”
Artists such as Rembrandt and Caravaggio famously used chiaroscuro to guide the viewer’s eye and create powerful emotional scenes.
In chiaroscuro paintings:
When used effectively, chiaroscuro enhances light and shadow in painting, giving artwork a sense of realism and drama.
One of the most effective painting skills is learning to simplify an image into two basic value groups: lights and shadows.
Step-by-Step Method
Artists often create tonal studies using a monochromatic palette such as:
These tonal studies help painters establish strong composition before committing to full color.
Successful paintings rarely happen by accident. Professional artists plan the lighting through value sketches and tonal studies before starting their final work.
Key Lighting Questions to Ask
By answering these questions early, artists can control the entire visual structure of the painting.
Planning lighting also helps artists apply chiaroscuro techniques more effectively.
One of the most powerful methods for controlling values is the use of underpainting techniques.
An underpainting is an initial layer of paint that establishes the light and dark structure of a painting before full color is applied.
Underpainting techniques help artists:
Common underpainting approaches include:
These techniques make it much easier to control light and shadow in painting.
Even experienced painters sometimes struggle with weak shadows or muddy mid-tones.
When this happens, the solution usually involves adjusting values.
Using underpainting techniques allows artists to re-establish strong values without losing the overall structure of the painting.
Learning to see values accurately takes practice. The following exercises can dramatically improve your ability to paint light and shadow.
Practice painting a 10-step value scale from white to black. This trains your eye to recognize subtle differences in value.
Create quick tonal studies of landscapes, still life, or reference photos using only one color.
These studies help you:
Removing color helps artists focus entirely on value relationships and contrast.
This is one of the fastest ways to improve light and shadow in painting.
A viewfinder helps isolate small areas of a scene so you can study values without distraction.
Artists who understand light and shadow in painting create artwork that feels dimensional, realistic, and visually engaging.
By practicing:
you build the foundation that great paintings rely on.
At the Yarnell School of Fine Art, we believe mastering value is one of the most powerful skills any artist can develop.
When artists control light and shadow, they gain the ability to guide the viewer’s eye, create atmosphere, and bring paintings to life.
So grab your brushes, practice your value studies, and let light and shadow transform your artwork.
God Bless, Stay Inspired, and Keep Painting! 🎨
