Dear Biil: As Mr. Kev rightly explained, varying the SOV opening time you should be able to control the no of droplets or the even the drop size. It also depends on the port size of the SOV. with 2 mm to 2.5 mm port size 6 to 13 ms pulse you should be able to control the drop. I use a Shako SOV 24VDC 2.3mm port size valve. Water head is baout 120mm. I believe, it would be difficult to control the drop ( both in size and numbers) if nozzle and port sizes are above 2.5 mm. You may wish to look at my set up at my website http://www.wingsofpassion.org.

With head of water about 600mm over the valve a 9ms pulse gave me one droplet.

Hi Kev, great set of water drops and a rally helpful tutorial thanks.
I have been trying some shots using a camera axe and through a Shako PU220AR 12v dc solenoid. The problem I am having is multiple droplets. I am unable to get a single droplet regardless of settings. Maybe a faulty valve? I just wondered if you had experienced a similar problem.
thanks in advance Bill

Cognisys made up an interface cable that links three Stopshots together.

How do you hook up 3 stop shot module together?!

I normally use something like a 12″ long baking tray with the image to be reflected propped up behind the tray. One flash aimed at the image from 6″ away and the other by the side of the tray 6″ away from the droplet. Depending on the position and angle of the camera you need to establish the ‘hotspot’ of the image flashgun so it is well illuminated.

Kevin: How far behind the water drop set up do you place anything to be reflected? I’d like to have some pictures of family and different objects reflected in the drops but am having trouble in the set up. Also am a little confused in where exactly to put the flashes…I have two 580exii
Thanks in advance for your assistance. Dave

I have been learning from the web many aspects of water drop photography. I have been experimenting on this for quite some time now and being an engineer myself went on to develop a professional kit. Details and some photographs of the water drop that I have taken using the kit is posted in my website http://www.wingsofpassion.org. I am also experimenting on smoke art as well.
Thanks,
U. Moharana

[...] Actually Kev totally puts me to shame with his great droplet photos here. [...]

I may have found a way to make this work. At the least something to look into further. As an experiment, I attached my bicycle tire pump the the stopper in the Mariotte Siphon. I barely added any pressure ( just the weight of the pump handle was enough) . With the nozzle at a slight angle there was enough pressure to change the trajectory of the water drop. I did have to change the pulse on the water valve down to 7.0 ms to get a single drop. I’m pleased, as soon as I get another valve and nozzle i’ll be trying this out with different colors
