DIY - High Speed Photography at Home

Freezing fast motion (AKA High Speed Photography), can give some pretty special photographic effects. High Speed Photography is used in physics, health research, sports and more. This guide describes how to capture super fast movements using ordinary camera gear and a little home made electronics. I will describes the setup I used the problems I encountered and what I did to solve or work around them. Here is a nice example of High Speed Photography

The inclusion of such images introduces many challenges. How do you manage the timing of exposure time

seconds greater than 1 / 6000?

We have to deal with a shutter lag, to synchronize the flash and the exposure time just in time.

However, shutter lag of a normal camera is so long that it will be even more impossible in the time of exposure. How to synchronize the flash with an exposure time of less than 1 / 6000 seconds?

To overcome problems with shutter lag and flash, exposure takes place entirely in a dark room. This image can be opened without actually getting the exposure. Exposure time just set the camera to work long enough to happen when the shutter is still open. Since the room is dark, a long exposure does not affect the final result (This is because the light does not penetrate the objective of hitting the sensor / film)

To actually get an "exhibition" is a flash was used. Flash Light will now be the real time

exposure time.

So now we have to see how long it takes the flash. It turns out that the power of the flash output, which in fact affects the duration of the light, in order to get shutter speeds. If you need exposure faster than 1 / 6000 seconds, the output is reduced.
