- Natural light comes from natural sources (sun, moon, stars) and varies in intensity and color throughout the day
- Artificial light is produced by man-made sources (lamps, flashlights, candles) and has more consistent properties
- Natural light tends to be softer and more diffused, while artificial light can be harsher and more directional
- The color temperature of natural light changes throughout the day (cooler in the morning and evening, warmer at midday), while artificial light has a fixed color temperature depending on the source
Hard vs soft light
- Hard light comes from a small, concentrated source and creates sharp, well-defined shadows with distinct edges
- Soft light comes from a large, diffused source and creates softer, more gradual shadows with blurred edges
- Hard light emphasizes texture and form, while soft light minimizes surface details and creates a more even appearance
- Examples of hard light sources include direct sunlight and focused spotlights, while examples of soft light sources include overcast skies and large window
Light and form
- Light interacts with objects to reveal their three-dimensional form and volume
- The way light falls on different shapes and surfaces affects how we perceive their structure and texture
Light on basic shapes
- On a sphere, light creates a highlight, mid-tones, and a terminator (the line separating light from shadow)
- On a cube, light creates distinct planes of illumination and shadow, with sharp transitions between them
- On a cylinder, light creates a gradual transition from light to shadow, with a highlight along the edge closest to the light source
- Understanding how light behaves on these basic shapes helps in depicting more complex forms
Light on complex objects
- Complex objects are made up of combinations of basic shapes, each with its own light and shadow pattern
- Observe how light interacts with the different planes and surfaces of the object, paying attention to the transitions between light and shadow
- Break down complex forms into simpler shapes to understand the underlying structure and how light affects each part
- Examples of complex objects include the human figure, animals, and intricate still life arrangements
Light and surface textures
- The texture of a surface affects how it reflects and absorbs light, creating different visual effects
- Smooth, shiny surfaces (metal, glass) reflect light more directly, creating sharp and well-defined reflections
- Rough, matte surfaces (fabric, stone) diffuse light more evenly, creating softer highlights and shadows
- Translucent surfaces (paper, thin fabric) allow some light to pass through, creating a glowing effect
- Depicting the interaction between light and texture helps create a sense of realism and depth in drawings
Shadows
- Shadows are areas where light is blocked by an object, creating darker regions that help define form and depth
