Thumbnails and Value Studies

Small, fast sketches that solve your picture before you commit.

10 min Intermediate

Professional illustrators and painters rarely start a finished piece directly. They first make thumbnails: tiny, fast sketches that explore different compositions. Ten thumbnails take fifteen minutes and can save you ten hours of fixing a bad composition later.

What is a thumbnail?

A thumbnail is a small drawing (a few centimeters wide) that shows only the big shapes and the big values. No details, no lines that don't matter. Its job is to answer: does this arrangement work?

Four quick value thumbnails of the same landscape idea, each with a different arrangement and value plan.

How to make thumbnails

  1. Draw small frames with the same proportions as your final piece (for example, 4×6 cm).
  2. Fill each one in 1–3 minutes. Speed forces you to think in big shapes.
  3. Use 3–4 values only: white, light gray, dark gray, black. A marker or the side of a soft pencil is perfect.
  4. Vary boldly: move the horizon, change the viewpoint, swap light and dark, zoom in and out.
  5. Pick the strongest one (or combine two) and develop it.

Value studies and notan

A value study is a slightly bigger thumbnail where you plan the value groups carefully. A notan (a Japanese term meaning "light-dark harmony") goes even further: only two values, black and white. If your design works in notan, it has a strong, clear structure.

You can turn any photo into a notan or a 3-value study with the Reference Studio:

Planning with values

When making value studies, think about:

  • Where is the lightest light and the darkest dark? Usually at the focal point.
  • What is the dominant value? Mostly light pictures feel airy; mostly dark ones feel dramatic.
  • Are the value groups simple? Can you describe the picture as 3 or 4 big shapes?
  • Does the eye flow through the picture and land on the focal point?

Exercise 1

Ten thumbnails

Choose a subject (a house on a hill, a cat on a windowsill, a person waiting for a bus). Make ten thumbnails in 20 minutes, each with a different composition. Circle your favorite.

Exercise 2

Notan studies

Find three photos of landscapes or interiors. Make a 2-value notan of each with a black marker. Then make a 3-value version.

Exercise 3

Master study

Pick a famous painting (search a museum website). Make a 4-value thumbnail of it. Notice how simple the value structure of great paintings often is.
