Smear detail along a direction to suggest movement in a still image. The treatment affects the photograph as a whole; it is not a subject-tracking blur.
When to use it
Architecture, nightlife, gestures and abstract compositions can work well.
How to control it
Amount controls the blend, Size the blur reach, and Rotation its direction.
A starting approach
Align the direction with the scene’s lines, then reduce Amount until enough structure remains.
Combine with intention
Choose one main direction first. Compare with the effect reduced or off before adding another treatment. Check the exported photograph as well as the preview.
