Don't forget that curtain shutters don't expose the whole picture surface at
the same moment: at high speed, it is merely a narrow slot between 1st  and
2nd curtain that sweeps across the film window.
BTW isn't the eye model  with its Persistence Of Vision better than
photographic model?
Image fades smoothly from retina in roughly 1/25 sec so last image should be
stronger than 1st
