Vertical-travel Shutters
Most modern 35 mm and digital SLR cameras now use vertical travel metal blade shutters. These work in precisely the same way as the horizontal shutters, but because of the shorter distance the shutter blades must travel (24 mm as opposed to 36 mm), the shutter blades can travel across the film plane in less time. This can result in faster flash synchronization speeds than are possible with the horizontal-curtain focal-plane shutter, and the shutter can reliably provide higher speeds (up to 1/8000 of a second).

Famous quotes containing the word shutters:
“The wind attendant on the solstices
Blows on the shutters of the metropoles,
Stirring no poet in his sleep, and tolls
The trand ideas of the villages.
The malady of the quotidian. . . .”
—Wallace Stevens (1879–1955)
