How to Write on the Wall With a Laser Pen

Laser pens are useful tools for directing an audience's attention to a key feature in a presentation or a specific point of a display. With some careful preparation, you can also use laser pens to create the illusion of glowing, neon writing on a surface, such as a wall. Writing on the wall with a laser pen requires the use of a camera that can mechanically delay the shutter speed. This will make the projected laser light taken in by the aperture over a duration of time appear in a photograph as continuous writing, as opposed to a singular point.

Instructions

1

Place a tripod for your camera approximately ten feet from the wall on which you will write with your laser pen.

2

Set your camera's shutter speed to at least three seconds. The shutter speed setting controls how long your camera's aperture will stay open. The length of the shutter speed is directly proportional to the amount of time you will have to write on the wall with the laser pen. While three seconds is plenty of time for shorter drawings, complicated drawings may require the aperture to be open for a longer period of time.

3

Install the camera on the tripod and adjust the position of the camera until you have the surface properly framed.

4

Turn all of the lights off in the room. Ensure that the room is completely dark so as to avoid extraneous light from entering into the aperture and affecting the shot.

5

Press the shutter release button (the button that takes a photo).

6

Draw your design, logo or words on the canvas surface at which the camera is aimed. Start drawing immediately after you press the shutter release button.
