For shots like this, I built a laser trap with a MIOPS trigger. It took a little time to build but my my small machine shop came in handy. Works like a charm.

Thank You Bozsik! Once again Your help is priceless! The "simplest" kit from COGNISYS is exactly what I'm looking for. As the price is 399 USD, it comes on the wishlist for Xst-mas (of course, everything else on that list will cost 450 USD mini.)




I have used their equipment for several years now. I think it is top of the line. The tech support from both Paul and Matt have been superb. I believe Paul is the engineer and designer of the equipment. It is great to get info from the person's involved in the designing of the products. They usually have a better depth of knowledge about what the piece of equipment is fully capable of providing. Good luck.

If you expand into some other applications for the device, I have a blog at naturescamera.com with many different techniques and shooting setups with illustrations. There are approximately 50 articles at the moment. It is all free. Just sharing what I know with others.

Very nice work. This is not easy to do.
You may want to study the world of Harold Edgerton. He was a pioneer in this field.

Lumix m43 bodies like the G9 can do high speed bursts, AND what is called a pre-burst to capture events before the shutter is tripped.

Of course, it's all about exact timing.
I want to fire the speedlights (2x) just at the moment when the water "strectches" and begins to fall down.
For now, I have to take tons of pictures to get 1 acceptable result.
It's always either too early or too late!!!

Has somebody an idea if there is a special device to release the shutter just when needed?

The problem is to synchronize finely the shutter realease with the optimum instant.
Do You believe a sort of "IR-fence" would be convenient?

As all the stuff was set up in the kitchen (stands/tripods/"geled" speedlights/DSLR/reflectors/background) I decided to shoot also what happened at the end of the "travel downwards".

Also a challenge timing. But then, there is a sound..."plop"...a sound sensor should be great to release the shutter.
Which one would You recommend?

Dan,
I recommend the high speed devices by https://cognisys-inc.com/. They have a device that is specifically for shooting water droplets. I have a few of their devices for the high speed stuff I capture. Technique is just as important as the equipment. It looks like you already have the technique and lighting down already.

I have attached two more difficult subjects to capture, but once you plan out the logistics of the target, you will be set to go.

Good luck.[/quote]

Eye-catchingly beautiful shots ⭐🎖️⭐
