Yeah for sure, it would take a freak accident to move your arms so quickly and suddenly and have them end up sharp in the end result.

The closest I’ve been able to achieve in a few minutes with my phone is a blurry vs non blurry image of my hand in the reflection vs in real life. Pretty hard to pull off this kind of double exposure trick when the software isn’t actually intending to take double exposures
