You've caught the timing well and its nice and sharp Steve, I'm struggling with these at the moment my current solenoid wont produce drops fast enough, I think i'm going to have to connect it to the mains water supply to get some pressure to force the water out quicker.
I've played with a few and struggle to get anything as good as those.
Here's my effort.
Apologies if I'm hijacking, but it should be obvious I need help with capturing the moment.
Currently I use off cam flash and guesswork.
Splog...tell me how to do that or go away ;-)
What kit is needed? a very dark 'room' and a speed flash?
How the flink do you get the focus right?
mind blowing....help me understand, my efforts have sucked...BIG TIME
