Default Challenge

Years ago I worked in forensics, and had the challenge of photographing 1. a lightbulb in the process of imploding, a balloon also, 2. capturing a .22 bullet piercing a blood soaked sponge, and 3. a freeze shot of water running out of a faucet. (A stream of water is actually a series of droplets as captured on film!). These tests were all accomplished using an ordinary camera (Nikon FE) a flash, and some odds and ends around the house. It would be interesting for someone duplicate these experiments. If there are any takers, I will explain my tests, with photos. (After the fact of course).

Singlepoint, Welcome

Closest thing to this I've done is water dripping from a faucet. I rarely use flash, and only onboard of a Fuji FP S3100. Are you thinking some sound-triggered flash, simple DIY possibilities?

I'm puzzled. Are you asking if there are people willing to participate in a thread of high-speed challenges?

Default Water

Interestingly enough, I found, that a smooth stream of water from a faucet, is in fact a series of droplets, as illustrated by using a flash, taken in a darkened room which causes the flash to fire at high speed.

The capture of a bullet passing thru sandwiched sponges, was accomplished by inserting 2 squares of tinfoil between the sponges, seperated by a thin tissue. Wires attached to activate the flash. After setting this up, the photo was taken in complete darkness, which commits the flash to the highest speed possible. When the bullet passes thru the sponges, and thru the tinfoil, the circuit is completed and voila, the speeding bullet.

A similiar experiment can be done, using a balloon or a lightbulb, for DIY high speed photography.

This sounds interesting. I'm not sure if my camera is up to it. (No external flash and no Hotshoe to attach one). If I can figure a way around these issues, then I'm in. This is a neat idea, and even if I don't get to participate, I will still be watching for others' results. Thanks for suggesting this.
