Light and dark
- Value 明度 is the lightness or darkness of a tone.
- A value scale 明度阶 runs from white through greys to black.
- Value is the strongest tool for showing three-dimensional form.
Value refers to the ____ of a tone.
Value is how light or dark a tone is.
Light on a form
- Light on a form has a highlight 高光, midtones 中间调, and a core shadow 明暗交界线.
- There is also reflected light 反光 and a cast shadow 投影.
- Reading these lets you make a flat circle look like a round sphere.
Which part of light on a form?
Sort each description by the light region it names.
The bold use of strong light and dark to model form is called ____.
Chiaroscuro uses dramatic light and dark to show form.
Select all regions of light on a rounded form.
Highlight, core shadow, and reflected light are light regions; the colour wheel is not.
Match each term to its meaning.
Value scale = tones; highlight = brightest; cast shadow = on the ground.
Contrast and chiaroscuro
- Strong value contrast creates drama and a clear focal point.
- Chiaroscuro 明暗对照法 is the bold use of light and dark to model form.
- Squinting removes colour and helps you judge value.
Squinting at a scene helps you judge value by reducing colour detail.
Squinting removes colour so you see the light-dark pattern.
Value matters more than colour for showing form. A drawing with correct value but wrong colour still reads as solid; correct colour with flat value looks flat. When a picture feels weak, check the value range first.
To draw a sphere, place a highlight where light hits, blend down through midtones to the core shadow, add a hint of reflected light on the shadow side, and drop a cast shadow on the ground. The flat circle becomes a solid ball.
Value is lightness/darkness, shown on a value scale. Light on a form gives a highlight, midtones, core shadow, reflected light, and cast shadow. Strong value contrast and chiaroscuro model form and create a focal point.
