Thanks everyone!

Here's my latest:



My first attempt was to hang a plastic bag over a pan filled with water, and using a trigger cord on the camera, I would try to time the drops to get a good shot.

The problems: The drops were of different sizes, no way to time them, and they never landed in the same place. It is almost impossible to focus if they don't land in exactly the same place. Also, I had my flash set on full power, and I would freeze the drops that were bouncing back up, but not the ones that were falling. Changing the flash to either 1/32 or 1/64 power enabled me to freeze the motion.

My next attempt involved "borrowing some supplies" from work. I grabbed an IV bag and a micro-drip tubing. This allowed me to get the same sized drops and have control over their speed and where they landed. This was a HUGE advantage as far as success rate. I was even able to capture collisions by gradually increasing my drip rate. It was still all very random, and it required hundreds of pictures for a few keepers. I kept on with this method for quite some time, and just by getting the timing down, and lots of pure luck I got some very cool shots.

I finally decided to upgrade the system,and ended up buying a Stopshot timer which controls the water drip rate, and syncs the camera and flash to the falling water. Even with the technology, is definitely not an exact science. I have been able to capture many more collisions, and as you can see by the picture above, by varying the delay in the drops and the delay in the camera firing, I'm able to capture different types of collisions. Its still very much trial and error, but with the timer, I'm able to concentrate more on fine tuning what I want to capture vs. shooting 1000's of shots hoping for a keeper.

My next chore is to improve my lighting with an additional off shoe flash, and then start experimenting with different liquids.

For those that just want to play around and see what they get, the bag of water with a pin hole will work, it just takes some patience and luck. Get you flash to fire as fast as possible by reducing the power. Try to get the drops to hit the same place in the pan, and stick a pencil or something into the water where the drops are landing, and focus on the tip of the pencil. If you have an assistant, it actually helps to have them hold the pencil at about the height you think the water is splashing which will keep more things in focus.

Hope that helps!

Starting to get the hang of this



I really like this one for some reason. Not the most beautiful collision, but something about the mirror sort of image and the freezing of the potential energy.

And my very first collision in a bubble!

These are marvelous. I especially like the second one in the first series--and the entire second series.

Top job in the second series!
Next time it rains and my roof leaks I will think of the pretty collisions happening.

Very nice series of drops! I have always been amazed at images much like these.

Thanks for sharing your experiences,

Scott
