Meaning and scope

Definition

Glitch effect adds offsets, fragmentation, or color-channel shifts to a finished image. It does not determine an actual malfunction, capture device, subject, or narrative.

In more detail

It indicates deliberate image-processing disruption. It is distinct from compression format, capture failure, local retouching, and compositing.

Includes

  • Deliberate offsets or fragmentation added to an image or region

Excludes

  • Actual device failure
  • capture-time blur
  • image compositing

What this does not imply

  • Actual failure
  • a particular device
  • subject
  • or narrative

Variability

The general source does not directly substantiate failure in a specific device or encoding method.

Usage and adjustments

Usage

  • Adjust disruption strength separately

Distinguish similar expressions

  • Distinguish it from actual device failure

Typical uses

  • Add deliberate disruption to an image

Possible failure modes

  • The image becomes unreadable
  • It becomes ordinary blur
