| Our Mission
Some common misconceptions about high-speed
photography are that it's only for experts and that it requires
specialized and expensive equipment. The HiViz 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
- FAQ
-- answers to frequently-asked questions about cameras, flash
units, cameras, and timing systems
- Links
-- high-speed photography resources on the web
- Galleries
-- portfolios of exemplary student work
- Projects
-- in-depth photographic studies of the "unseen" world
Our Name
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 videotapes of high-speed phenomena. (see Video).

Our Logo
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 to the right for the HiViz logo. The multiple-image
photograph of a milk splash was taken by Brett Goldstein and
Loren Winters at the North Carolina School of Science and
Mathematics. 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.

Use of Our
Materials
We provide our materials for non-commercial
use especially by students, teachers, and hobbyists. We
require that you ask our permission for such uses as publication or exhibition in either
printed or electronic form or for any use intended to generate
income or publicity.
We
want to know about your high-speed photography projects. We're happy
to provide advice and support as needed. Your work could even end up
being displayed here.

The Author
Loren
Winters, a high-school physics teacher and creator of the HiViz
site, has been mentoring middle- and secondary-school students in
high-speed photography projects since 1984. He has conducted
workshops and presented public demonstration lectures in high-speed
photography throughout the country. Dr. Winters teaches high-speed
imaging as well as physics at the North
Carolina School of Science and Mathematics in Durham, NC. His
high-speed imaging students start out the course by taking jumping
self portraits like the one to the right. The sound of a hand
clap at the peak of the jump sets off a sound trigger which
discharges a flash unit to capture the action. Check out some recent
projects by NCSSM students.
