I show how to use a few dollars in parts from your local hardware store to improve a laser trigger on the Camera Axe. I basically use some PVC parts to create mounts for the laser and light sensors. This makes them weather proof, easy to mount on a tripod, and easier to align due to a diffuser in front of the light sensor. http://www.cameraaxe.com

The airgap flash works well up close, but it would be nice if the light was more focused so it could be placed further from the target. Here I use laser cut acrylic pieces to build a reflector for the airgap flash and then test its performance.
Continue Reading →A few tips and tricks I use to get the focusing correct for liquid droplet photography. The main tips suggested are using live view, a focus chart, and a focus rod to align droplets.

Some people were looking for a protective case for their airgap flash. After some research I decided to try the Pelican 1550 case.

This video shows how to use two valve sensors with the Camera Axe to collide different colored droplets. In my searching few people have accomplished this advanced droplet technique. This video takes you step by step through the process of capturing these impressive shots.
The airgap flash is for sale at Information Unlimited. A little history of the Airgap flash development is also discussed.
The second portion of the video gives a quick overview of Alan Sailer’s book “A Book of High Speed Photography”.

In this episode I do an overview of the new air cannon I made to help take high speed photos with the Camera Axe of new interesting targets.
Check out http://www.spudfiles.com if you want more information about building an air cannon.

The biggest improvements are using white acrylic for the reflector, reflector design improvements to better hold the flash tube, and some interesting findings from using a Fresnel lens.

In this video I describe how to take photos of flying ball bearings shot from an air cannon. I also go over the different energies in this versus an air pellet, and how that kinetic energy gets distributed into the target.
UPDATE: Alan pointed out my energy calculations were off by a few orders of magnitude and wikipedia confirmed it (http://en.wikipedia.org/wiki/Joule). The units for Joules are kg*(m^2)*(s^2). My units were g*(m^2)*(s^2). So to ...
