Collision

Further playing around with the Pluto Valve today and I think it's getting better.  We were getting motion blur before, and focussing was difficult, so we swapped out the new Elinchrom light for a Nikon Flash.  This has the power turned all the way down, but is very close to the water.  This gives a really quick flash, quicker than the 1/4000 of a second I was getting on the camera, an so it freezes the motion better than the other light did.  This in turn makes it easier to get the focus right.
