Why is it so hard to capture shape and volume?

Struggling to define volume and shape is one of the most common challenges for painting students. Volume represents the three-dimensionality of objects, making them appear real to our eyes. If your paintings lack volume, it means your eye is not yet fully trained to perceive and replicate tonal values accurately.


Training Your Eye to See Volume

Developing volume in painting requires visual training. As artists, we spend countless hours observing color mixtures, objects, textures, and transparencies. But simply looking at things isn’t enough—we must actively analyze details, paying close attention to:

  • Shadows
  • Highlights
  • Reflections
  • Contrast levels

This ability to observe and interpret tonal variations is what allows us to create depth and realism in our work.


Using a Cube to Understand Tonal Values

To improve your understanding of tonal values, try painting a simple cube in any color of your choice, preferably using tempera or acrylic paint. These dry quickly, allowing you to repaint as needed.

The cube serves as a visual reference for the three main tones used in painting:

  1. Shadow (darkest side)
  2. Midtone (middle tone)
  3. Light (brightest side)

If you’re painting a lemon, for example, observing a cube in the same color will help you distinguish the necessary shades. To enhance brightness, simply add white to your mixture.


Mastering Soft Transitions and Blending

Achieving the smooth, curved surface of a lemon—or any rounded object—depends on practice with brushwork, especially blending techniques. Start with the cube exercise to grasp the basics of tonal contrast, then gradually introduce more variations to your color mix. Remember, not all lemons are purely yellow—some have greenish areas, subtle color shifts, and reflections.

With experience, you can refine your technique using glazes, allowing you to create stunning, realistic artwork.


Final Thoughts

Defining volume and shape takes time and practice, but training your eye to see and replicate tonal values is the key. By starting with simple exercises like the cube, you’ll build a strong foundation that will improve your ability to paint more complex subjects with depth and realism.

Keep practicing, and soon, your paintings will gain the three-dimensionality that makes them come to life! 🎨✨
