Shooting Water

[xd9user]

Been doing mine by hand and haven't gotten a collision yet. Pretty Cool!

Trying to capture a collision by hand can be almost impossible because of the short duration of the event. Some people have limited success with a bag of water with a small pinhole for a drop source. I built a valve timer based on the Arduino micro processor and some 555 timers. The Arduino controls the valve and the 555 timers control the flash timing and trigger. The CameraAxe box does both functions relatively inexpensively. Another major key to success is a valve that is repeatable. The Shako Valve works great for this application.

Here is a link to a man that has invested a lot of time in water drop collision photography. It is where I learned about the Shako valve. It is a tremendous read if you are at all interested in this aspect of photography.

Thanks guys, the way my rifle shooting has gone recently it's good to shoot something decently.

Maybe this new barrel waiting on me.

I can't seem to get a handle on how to take a good series of pictures of a vibrating rod yet for the rifle tuner argument. Just wanting to clearly demonstrate the shape of an actual node that cannot be misconstrued. I've thought a double exposure with different colored strobes - but I haven't managed to get my meager photo equipment to even catch a clear image yet.
