How to create light art or street light graffiti :

This are the basics (provide by LightFactor):

To get the best results you need a tripod. The exposure should be around 10-30 sec. or longer if needed. Stay in front of the camera and do your writing. To not overexpose set the camera to about iso100, and close your aperture as much as possible. If there is still too much light, you might have to use a nd-filter. It is always nice to integrate the surrounding into your picture.

We use flashlights, biking-lights and flashing LED lights they all work with batteries, so that we are mobile, you also get nice results with fireworks & torches .

We use 3 different type of lights:

Xenon: makes a warm golden light.
LED: makes a thin precise line.
Cold Cathode: thick line/fat cap.

But the best results you get by experimenting, use filters and things which reflect light…

Now you can do your thing!
