Start your light graffiti experiments by drawing words in light. You can send a romantic light graffiti message to a lover, or a sweet, motivational message to a friend or family member. Using light graffiti words, you can write a digital postcard to a friend in a faraway place. You can also make commentary in light graffiti on a nighttime scene you photograph. The next time you have a short phrase you'd like to express in a new way, from poetry to puns, use light graffiti.
Use light graffiti as your pen, and the air as your sketchpad, to create light graffiti art. Use this technique to create a finished piece or as a drawing exercise. You can give finished light graffiti sketches as gifts or print them for sale. Artist Gjon Mili photographed Pablo Picasso doing light graffiti sketches 1949, making for a famous collaboration featured on the cover of "Time" magazine.
Experiment to make something pretty for the eyes. Use many colors and textures of light in your light graffiti. Make geometric designs or over-the-top fireworks of light. You don't have to lay it on thick to create something fun to look at. A few lines or spots dynamically placed will go a long way toward creating interest for the eye. Remember that the darker the room in which you photograph, the more the light itself will stand out.
Incorporate your light graffiti into the rest of your photographic content. Use it to outline objects or people, or to add ghosts to the rest of the photographic setting. You can use the light graffiti to emphasize the most obvious part of your photograph or to highlight content that might otherwise go unnoticed. Use the light graffiti itself as a symbol for technology, enlightenment, temporality or any other other concept you see fit.
