This look can be made in-camera with a slow shutter and flash, not necessarily Photoshop.

What’s happening is a mix of ambient exposure and a flash burst on a moving subject:

• The ambient light records the subject’s movement during the longer shutter time.
• The flash briefly freezes the subject sharply at one point in that exposure.
• Because the subject moves, the ambient-recorded silhouette becomes offset from the flash-frozen figure, creating that graphic outline effect.

In the example, the outline appears ahead of the subject, which suggests first-curtain sync: the flash fired near the start of the exposure, then the subject kept moving during the remaining ambient exposure. With second-curtain sync, the trail/outline would appear behind the subject instead.

An off-camera flash helps define the subject more clearly and gives a directional, dramatic look. Positioning it slightly to one side and above can emphasize shape and separation.

So the key ingredients are:

• slow shutter speed
• moving subject
• flash to freeze the subject
• sync timing (first- or second-curtain)
• likely off-camera flash placement

Any editing is probably minor styling/toning rather than the main effect.
