Step 1: Camera and settings

The first thing you need is a decent camera such as this Nikon coolpixs6 from http://www.nikonusa.com

Next is the most critical part in the whole process, set the exposure to around 4-6 seconds.

Step 2: The laser for writing

Most lasers will do but it helps if you have a decent quality laser that will not fall apart a few minutes of use. Color is a matter of preference, i personally love blue lasers so i'd go for the Spartan from Dragonlasers at http://www.dragonlasers.com

The beam itself does not need to be visible for the photo, just the beam point. This means you can use low powered lasers during the day and still take effect pictures of laser writing. Dark conditions will give the best effect though.

Step 3: The writing itself

This is the hard part. Depending on the exposure settings in step one, you have roughly 4-5 seconds to quickly write your message with a shaking hand before time runs out.

The first few attempts will be a mess so give yourself time to practice and you'll get some pretty amazing results.

Sad day. i buy everything off ebay because it tends to be cheaper. I wanted to get a blue laser pointer, but it wasn't that much cheaper. My green one (off ebay) was $3 with free shipping (shipping took about 3 days). The one off amazon was $17 plus shipping. But the blue lasers were roughly the same price. I guess I'll still with green. :/

This Is A Really Cool Project And It Works Great With A Red Laser, What Made It Better Was That instead Of A Wall I Used A Glare Free Projector Screen. I Do Have One Thing I Want Someone To Try, Take This Instructable And Combine It With This One---->http://www.instructables.com/id/Laser-Pointer-Diffuser/
And Instead Of Pointing With It, You Can Do Some Sky Writing. All You Gotta Do Is Stand In front of The Cam And Draw. Ill Try It Out But I Might not Piu An Instructabel If It Fails So Just BE On The Look Out For It. Any way This Is A Cool Project, I Gotta Get A Green And Blue Laser. 5*

No. These photos were done with this laser http://www.dragonlasers.com/aurora I used the pic of the Spartan in this instructable because it looks so cool :)
Does this work with regular red lasers as well, or only blue and green lasers?
look on comment above... if u can see a red/blue/green/any-color dot, it will work
grannybasher (author)  grannybasher6 years ago
It will work with any laser that has a visible beam point.
Apparently that is a sotra high price for a laser. From the same place you can get a 10mW blue laser for $700. He has a 40mW blue laser but you can also go one step up and get a $1,500 60mW blue laser
No he used paint. JK.
possible with a red laser???????????????????????/

omg, really expensive!
*Sigh*. Blue lasers. I love them, I wish I had one. Too much $$$ though. Awesome Instructable though, I can never figure out how to set the thing on my camera to whatever seconds. Awesome Instructable once again, and cool laser.

that's cool, 'specially as it's smaller "writing" than a torch. =)
