With a laser and long exposures photography, you can create some works of art on your walls.
A list of items needed.
A tripod for the digital camera.
A digital camera with manual shutter settings that allow BULB or at least 3-5 seconds.
Most cameras have this ability.
A good quality laser like my Wicked laser Classic.

Step 1: Setting Up Camera.
Place digital camera on tripod and position far enough from wall to allow for a wide angle view of the wall you wish to write on.
Now would be a good time to learn where the bulb setting, or manual setting is for your camera.
Most cameras have the setting for manual, look on your selector wheel on the camera for the RED M or red picture of a camera with a hollow circle in the middle.
Those are the 2 basic icons for the manual setting.
Using the shutter speed, set it until you either see BULB light up on the screen, or use a setting like 3,4 or 5 seconds.
Bulb will allow you to shoot as long as the button is pressed, but this poses a problem, because you can't hold the button down while you are trying to write with the laser.
Unless you have a wireless shutter transmitter.
For sake of ease, just find a shutter setting of a few seconds.
Second step is to set the camera to a low enough ISO rating so that the room won't be overexposed during the long exposure.
It helps to have a room that has a dimmer light so you can infinately adjust the rooms ambiant light, but this is not necessary.
Start with an ISO of 100.
If you can also set the digital F/stop, set it to F6.7 or F8
Or anything in that range.
The other settings faster settings like F3 or F3.6 and so forth will just make the image to bright.
Now set your timer, so you can have a few seconds to compose yourself before drawing.
Step 2: Practice Drawing
You can also practice what you want to draw ahead of time.
When writing words, you have to turn on the laser and back off again in between letters, because remember, the camera is picking up the streak of green, and will see everything you do.
In my pictures you can see there are a few different things going on.
Snap the picture and start drawing.
Try to keep an eye on the camera while taking the shot, you can usually see the screen go dark during the exposure, then become visible again when the exposure is complete.
Try a few.
Step 3: I Took 3 Different Images, Due to Shorter Exposures
You can be as elaborate as you want by taking many exposures and stacking them into one final image with special software.
I am using a trial version of Photomatix Pro, but most programs like Photoshop have the ability to align and stack mulitple images.
This is a whole new learning curve, but if you can manage one single exposure, your off to a good start.
Step 4: The Final Product
Here you can see the final image.
I have found that green lasers work the best, I have tried a Red laser, but the image does not appear on the picture.
Perhaps a higher powered Red laser like the ones from Wicked Lasers would work.
Any of the green lasers will be sufficient.
