Some common misconceptions about high-speed photography are that it's only for experts and that it requires specialized and expensive equipment. The HiViz.com site is dedicated to dispelling those myths by providing...
- Tools -- instructions for setting up and using your own high-speed imaging system, including triggers, flash units, cameras, and timing devices
- Activities -- guidance in photographing and demonstrating bursts, pops, snaps, smashes and splashes
- Links -- high-speed photography resources on the web
- Galleries -- portfolios of exemplary student work
- Projects -- in-depth photographic studies of the "unseen" world
Why do we put the word, visual, in High-Speed Visual Imaging? Many people think that high-speed phenomena must be photographed to be seen. In fact, such fleeting events as balloon bursts, rebounding tennis balls, and liquid splashes can be seen with the human eye under the illumination of a brief burst of light. While we can't show you live demonstrations here, we do provide video clips that show you what you would see and hear. We also provide descriptions of how to perform some demonstrations (see Teachers), and how to produce your own video of high-speed phenomena (see Video).
The splash of a drop of liquid is perhaps the most recognizable and prevalent of all high-speed images. A. M. Worthington first photographed splashes more than a hundred years ago. His book on the subject, A Study of Splashes, is a classic, although it's not well known to the general public. The person who made the image of the splash coronet familiar to the general public was Harold Edgerton, former MIT professor and father of high-speed photography in the 20th century. He spent years trying to photograph the perfect splash.
We added our own twist to the photography of splashes and chose the image shown above for the HiViz.com logo. The use of colored filters on 4 flash units provided visual separation of overlapping images. For more information on how this photograph was taken, click here.
