I have been experimenting doing water droplet collisions and not coming close to what I want to achieve, e the almost mushroom shaped collisions. I am using a liquid that is slightly more thicker than water, 2 off camera flash, ISO L01, 2 second exposure and F16. I made a mariotte Syphon with a controllable outlet valve increasing or decreasing the droplet rates. Is there a specific height that you have to have the Syphon above the catch tray? Any info would be greatly appreciated please. Also I am using a fairly shallow backing tray to catch the drops with only a cm of water covering the bottom, also tried it with the tray being nearly full.
 
Ashmash iirc wrote a really good tutorial on it, it is in the tutorial section, sorry I can't link to it I am on my phone.

I also seem to remember that he used rinse aid in the water to reduce the surface tension of the water.

I'd love to try this at some point, so will look for that tutorial myself. Julian, out of interest, what results are you getting at the moment? By which I mean, how are they wrong compared to what you'd aimed for?

Just remembered the post when I first started doing these, I had completely forgot the tutorial as Id already posted on it :cuckoo::bonk:
 
Depth of field is allways an issue with water drop photography.
The front focus point is critical 1/2 - 1 inch in front of the impact usually works best.

Your eyes are used to things getting out of focus with increased distance

I use 1/200 f/16-20 flashes set to 1/32 or 1/64 power

Hi Andrew

I am the manufacturer of the SplashArt Kit that controls the water and camera timing
so repeating the shots is not a problem.

I can post a video of the kit in action if I am invited to do so.
I dont want appear to be Spamming the forum.

I would like to see that if the mods have no objection.
 
The blobby picture was created using a Xanthan Gum solution thinned with Nature Clean All Purpose Cleaning Lotion, Dettol Power and Pure Kitchen can be substituted for this.

The first drop size is increased untill you hear plop and also get a spike. You may have to alter the nozzle height.

The Second drop is then brought in. By overloading the nozzle on the second drop you will produce more than one "second drop"

A long enough camera delay will allow the third drop to collide with the crown formed by the second drop.

As you can see there are loads of variables so no two drops are ever the same.
