Vela Flash Strobe
Another feature that the Vela flash has is a strobe mode. It can put out up to six flashes spaced from 10 to 250usec. Years ago I spent a lot of time making a deal delay flash controller that would fire my two microflash units in sequence with an adjustable delay. I never found a good photo to make with the set-up so I moved on.
Part of the issue is that you get the best results by using a non-reflective background because as the action moves the light from consecutive strobes will bleach out the earlier exposure making the objects look like ghosts.
So for this photograph I set up a hefty razor blade and shot a small lead ball at the blade. You can see how the impact torqued the blade and you can clearly see how the lead ball is cut neatly into two slices that fly apart.
The flash duration is 2usec and the separation is a guess at about 150usec.
I used my new D750 for this shot because it has much lower noise compared to the 5D Mk II.
This is the same stupid shot done with a microflash.

A third hot weekend in store. It's getting very old.
Cheers.
