Juggling Time-Lapse Video in Austria Explained

juggling time-lapse video in citySomething quickly moving, like, you would think, balls being juggled, isn’t a good subject for a time-lapse sequence. The juggling time-lapse video below, however, looks amazing; like the balls are held in their patterns as streaks. It was produced by Lukas Trötzmüller and Joachim Hering, and was meant to highlight the juggling scene in Graz Austria and as an experimental movie.

I had no idea this was a common thing there, but it sounds like a really interesting place to visit.

The video looked to me like since the juggling is done in a repetitive motion, the balls appear to stay in one place as a streak. The answer is quite a bit more involved, and I was able to catch up to Lukas for the rest of the story after the video: Continue reading

A DIY GoPro Handle Light


“Gopro Team Waalwijk” wrote in to tell us about a method for attaching a light to a GoPro handle. The video is mostly about how to properly attach zip-ties to attach the headlamp to the handle. As seen after the “read more,” it’s well-produced, and the resulting video, taken on a Hero3 Black in otherwise total darkness, can be seen just after the 3:00 mark. Continue reading

Thermal Leak Detector Long Exposure Photography

A little over a year ago, DIYTripods featured a technique for taking heat-sensitive long exposure photos using a modified flashlight. The photographic process behind this is explained there. This gave me an idea that one could use a Black & Decker TLD100 Thermal Leak Detector (Amazon) without modification to do the same thing.

The unit functions pretty simply. You turn it on pointed at whatever you want to appear normal temperature-wise, and it displays green.  Point it at something cooler and it becomes blue; point it at something hotter and it becomes red.  To make an infrared image, photograph your target while slowly sweeping the red-green-blue beam across, and you have a crude infrared photograph. Between 25 and 30 seconds of exposure seems to work well for me.

The one thing that is kind of tricky is that the color transition isn’t instantaneous, but it’s not impossible to work around. In addition to what’s above, I’ve taken some other interesting photos using this technique, as seen after the “read more” link. Continue reading
