TPB #89 – Help Design the Best Lightning Photo Tools

Posted by:

This video shows a work in progress of some great software that Dan and PTB have been working on to improve the ability of the Camera Axe to photograph lightning. While the Camera Axe was already pretty good at photographing lightning this makes a number of significant improvements to that software. I encourage others to join the forum thread below and help design the best possible software update to photograph lightning. Some ...

TPB #74 – Air Cannon

Posted by:

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 ...

TPB #45 – Automated Finish Line Photos using the Camera Axe

Posted by:

In this week’s video I talk about using a motion/distance sensor with the Camera Axe to automatically take photos of people running a race. The sensor will detect a person running past and then trigger the camera. In this video I go over the Camera Axe setting, camera Settings, and then do an example run (pun intended).

I found this use of the motion sensor to work very well. I expect it would ...

TPB #42 – Do Optical Slave Flashes Work with High Speed Photos

Posted by:

In this week’s video I look at the lag introduced by using a master flash to optically trigger a slave flash. Then I look at this extra lag and see how that would impact some common high speed photography cases like photographing a moving bullet and water droplets.

* Video about measuring Flash Lag
* Video about measuring Flash Duration
* Video about the MultiFlash board

TPB #28 – Hardware Improvements for Camera Axe 5

Posted by:

This week I highlight the hardware improvements from the Camera Axe 4 to the Camera Axe 5.

  • The Camera Axe 5 no longer needs a special cable to reprogram it. It uses a standard USB cable and that cable is included. Reprogramming to the latest software is a huge selling point and many of the improvements from Camera Axe 4 to Camera Axe 5 are in the software so they aren’t mentioned on this ...
