Explanation:
Artworks that exhibit a full range of value are generally successful. It doesn't matter the type of art you are creating. As long as there are dark values in harmony with light values, your artwork will most likely be aesthetically pleasing. A full range of value means that they are ample amounts of light values- called tints, and dark values - called shades. To be sure that you have a full range of value in your artwork you may create a value scale.
Using a value scale, you can be sure that you create a full range of value. Many artists use a value scale as they work, identifying specific values and adding them in appropriate spots.
The whole point to value is to create the illusion of light. So value is used to basically create the illusion of highlights and shadows. Highlights and shadows combine to create the illusion of a light source. Remember, without light we cannot see. So technically, without a light source, you have no illusion.
This is why value is mentioned so frequently on all of the art instruction videos and pages on this website. It's important. If you understand and implement value correctly in your drawings and paintings, you will see immediate improvement. Value is essential to success.
