DSLR Shutter at 10,000fps

Interesting slow motion study of a DSLR shutter/mirror action. Note just how much mirror bounce there is and also the width of the slit in the shutter at different shutter speeds.

Interesting in that the 'speed' of the shutter stays the same but the 'aperture' of the shutter changes. Very clever. Also very clever is the dampening of the mirror on opening and the time lag between the mirror raising and the shutter opening to avoid movement blur. Mirror bounce on 'returning' is not effectively dampened as it doesn't really matter as the shutter is now closed. Very fiendish these Orientals. :)

It also nicely demonstrates why for flash photography, the camera sets the shutter speed to the "flash sync" speed. It's the fastest shutter speed available where the first curtain has cleared the sensor before the second curtain starts to close. If the flash fired at a faster shutter speed, only the sensor area behind the open slit would be exposed.

I think the article is named incorrectly... it has nothing to do with 10,000frames per second.... they recorded a shutter at 1/8000th of a second... but that is a very different thing....

Aside from that, it's a very interesting video! I'm glad I watched it, although I had some form of idea of what was going on, I had never looked into how it all worked.... very good.

thanks P38Rover!

But the camera they recorded that 1/8000th with, was filming at 10000fps. I think that was where the title came from.
