This style is commonly called chronophotography, and it’s also often described as sequence photography.

To make one, you capture a series of images of the subject moving through the scene, then combine the frames so the subject appears multiple times in a single final image. Common ways to shoot it are:

• burst mode for a rapid series of stills
• an intervalometer for regular timed shots
• video frame extraction if lower resolution is acceptable

A tripod helps keep the background aligned, which makes compositing much easier. Using manual exposure and manual focus helps prevent changes between frames. Planning the timing matters, especially if you want clear separation between positions or need to handle overlapping subject positions.

In post-processing, the usual approach is to align the frames if needed, then mask or cut out the subject from each frame and combine those subject positions onto one background. Overlap between positions makes the masking more difficult.

As with most action techniques, good results come from testing and refining your timing and setup.
