You'll note that the cloth parts of a focal plane shutter were
referred to as 'curtains' or blinds' - both window terms.
And we still talk about 2nd Curtain flash synchronisation although
they are metal blades these days.
I loved the old Contax/Kiev shutter which was like a segmented roller
blind with a unique noise.
Shutters 'shut out' the light.
Fiat lux.
