Interesting. I've played with similar things on a realtime motion blur effect a
few years ago. I assumed the shutter time could be adjusted (to control exposure
as well as motion blur, much like the aperture does for focal blur) but I never
actually researched what real cameras do. Is it always 50%?

The thought occurs that you might get a more film-like effect if your first and
last sub-frames had a gradient to black on them, to simulate the blur of the
closing shutter! But I'm probably over-thinking this.
