Motion blur is how cameras record movement: anything that moves during the exposure smears along its direction of travel. Adding it afterward injects energy into a static photo — cars look faster, dancers look mid-flow, street scenes feel alive. It is also a staple of poster design, where streaked backgrounds give text and subjects a sense of momentum.
Distance controls how far pixels streak, and Angle sets the direction — horizontal for passing traffic, diagonal for something more dynamic. Use the Strength slider to blend the blur with the original: at partial strength, the sharp image ghosts through its own motion trail, a classic sports-photography look.

How to add the motion blur effect to a photo
Tips for the best motion blur look
- Match the angle to the natural direction of movement in the photo — a runner blurred vertically looks wrong instantly.
- Partial Strength (50–75) keeps a sharp “anchor” of the subject inside the streaks — often better than full blur.
- Motion blur + a dark background + bold text = an instant sports or music poster.
Motion Blur effect — FAQ
How is motion blur different from regular blur?
Regular (gaussian) blur spreads pixels equally in every direction — it looks soft. Motion blur smears pixels along one straight line, which the eye reads as movement. Same math family, completely different feeling.
Can I blur only the background to make the subject look fast?
A classic technique: export a motion-blurred copy, then combine it with the sharp original in a layered editor, masking the subject. Within this tool, partial Strength gives a similar ghosted-speed effect in one step.
What angle should I pick?
Follow the horizon or the subject’s travel direction — usually 0° (horizontal) for vehicles and landscapes. Small diagonal angles (10–20°) add drama; vertical (90°) suits falling or rising subjects.
