Expected changes

• A scene with fading natural light and increasing darkness is more likely to appear.
• The transition from daytime toward night is more likely to be readable.

Definition

Dusk is a low-light time and light environment transitioning from after sunset into night. It does not determine the appearance of sunset itself, particular weather, place, emotion, season, or culture.

In more detail

It centers on remaining daylight that gradually fades toward nighttime darkness. Sky color, clouds, artificial lighting, and a person's emotion remain separate choices.

Includes

• A low-light period transitioning from after sunset into night.
• An environment with gradually fading natural light.

Excludes

• Sunset itself with a visible sun.
• Particular weather, place, emotion, season, or culture.

What this does not imply

• Sunset itself or a visible sun.
• Particular weather, place, emotion, season, or culture.

Variability

Light color and brightness vary with clouds, region, season, and exposure.

Usage

• Use it for the time and light transition from after sunset into night.

Distinguish similar expressions

• Specify sunset itself, weather, place, and emotion separately.

Typical uses

• Add dusk light to an outdoor or indoor scene.

Possible failure modes

• The result is as bright as daytime, so the transition toward night is not readable.
• A visible sun or particular weather becomes mandatory.
