Meaning and scope

Definition

Light trails are a temporal visual effect in which moving light sources appear as continuous lines or bands. They do not determine a light source, camera setting, location, or mode of travel.

In more detail

Lines of light indicate a path of motion. They are distinct from afterimage, blur, and a stationary luminous object.

Includes

  • Continuous lines left by moving light sources

Excludes

  • A particular light source, camera setting, afterimage, or simple blur

What this does not imply

  • A particular light source, camera setting, afterimage, or simple blur

Variability

Trail length and brightness can be adjusted separately.

Usage and adjustments

Usage

  • Use it as motion made visible by light

Distinguish similar expressions

  • Specify afterimage separately

Typical uses

  • Show the path of a moving light source

Possible failure modes

  • The light source appears stationary
