Those missing halos are not a failure of vision but a feature of it. A camera sensor, locked in long exposure, behaves like a patient accumulator of photons, summing every tiny packet of light that hits each photosite while the shutter stays open, so a fast-moving spark is written as one continuous trail across the frame.
Human sight, by contrast, is built to erase that trail. Photoreceptors reset quickly, and the visual cortex applies temporal filtering and saccadic suppression to prevent motion smear, turning the same spinning steel wool into a sharp, jittery spray instead of a ring. Your eyes run on short exposure, roughly a few tens of milliseconds at a time, discarding most of the path so you can track objects and avoid blur. The sensor runs on integration time and exposure latitude, welcoming blur as data. Where biology prioritizes real-time edges and stability, silicon rewards duration, quietly stitching moments into a halo that never quite exists in any single instant at the temple itself.
