Surround me with long-exposure motion echoes

Edit my uploaded action or full-body photo into a believable in-camera long-exposure portrait. Keep one final version of the adult subject perfectly sharp and recognisable at [FINAL POSITION], preserving identity, outfit and body proportions.

Motion sequence: show [NUMBER] semi-transparent echoes tracing [ACTION PATH] from [START] to the final pose. Each echo must represent the same person at a logical moment in the movement, with progressively changing opacity and continuous limb motion.
Environment: [SETTING] remains stable and sharp, with only physically moving lights or objects allowed to streak.
Lighting: rear-curtain flash freezes the final subject; ambient [COLOUR] light paints natural trails during a [SHUTTER LENGTH] exposure.
Camera: locked tripod, [LENS], realistic motion blur and no digital cutout edges.

Do not clone identical poses, create extra solid people, add limbs to one body, blur the final face or use smoky ghost effects. No text, supernatural styling or background regeneration.
