Thank you. Awsome technique! ....and maybe other light sources can be used as well.....hummmmm. Example, what about beaming a light on brightly colored glass swinging??? What do you think? shu

Thanks for the good words. My older brother and I used to do this long long ago in a galaxy far far away. We were both teenagers at the time. It was fun then and it was fun now.

Here's how it's done:

First, get a small flashlight. Tie a string to the end of it and fasten the other end to the ceiling. Set the camera, on manual mode, under the flashlight pointing straight up at the flashlight and set the exposure for 10 to 15 seconds and aperature at f22. In a totally dark room swing the flashlight and fire the camera. This will give you a simple oval that is sprialing down.

Second, create a double axis pendulum. Hmmm, let me explain. Take a peice of string about 3 feet long and fasten it to two points on the ceiling about 2 feet apart. Then take the string from step one and fasten it to the second string. This gives you a pendulum with different swing frequency on the two axis. It will give you a much more complex pattern. Again swing the flashlight and take the picture. This is what I've got here.

Import the picture into PS and play with the settings.
