Echo
The same shape repeats at a fixed delay, each repeat stepped and fainter — an audio delay made visible.
Visual traits
- A mark appears, then the same mark repeats several times at a fixed time interval
- Each repeat steps by the same amount: outward for rings and frames, toward the center for lines
- Repeats get thinner and fainter, and shift toward a cooler color, until they disappear
- The original mark does not travel; the repeats come from time, not from movement along a path
Prompt
Echo effect: a single ring appears on the rule-of-thirds point and repeats four times at a fixed delay, each repeat a step larger, thinner and fainter, shifting from warm to cool before it fades; the original does not move, like a dub delay made visible.
Negative prompt
motion blur, trail along a moving path, ghosting from camera shake, random scattered copies
