I'd like to see someone attempt a Van Gogh.

I knew that crate of 200 glowsticks off ebay would come in handy someday.

I've always seen it referred to as light painting. But oh well, that's not really all that important.

Here's mine. [sapidexistence.com]

It was a joint effort between my brother and me. I wish the background was darker, but I also like how it's not like everyone else's.

I remember doing this way back in junior high with our Photography club teacher. We only used a flashlight though and used black & white film.

I didn't move the flashlight around much but pointed it in different directions from where I was holding it. The outcome looked like I was holding a ball of light.

Fun times.

This is actually a growing type of art form. I remember first finding things like this with the Sprint commercials, and recently I came across this article online showcasing work of these artists:

10 Amazing Light Graffiti Artists and Photographers

I photographed a wedding once where instead of rice or flowers, the guests were given large sparkles. I was able to get a picture of one guest making a heart with his sparkler. It came out really well and I made it the last photo in their album. Needless to say, they loved it.
I love doing this kind of stuff. And it's pretty easy once you figure it out. Now it's super cheap to experiment with digital.

I had to do some photography for a college class about a year ago. While I was experimenting, I tried the longest exposure time my cheapo camera could do (2 seconds (I think)). So while moving the camera at my pulsating multicolor mouse I caught this: [img509.imageshack.us]
I pulsed my laser pen into my microwave, and moved the camera around, and I accidentally caught Katey Sagal's name from the Futurama credits off of my TV; very interesting: [img255.imageshack.us]
Three directional camera movement while looking at my peephole; my favorite: [img90.imageshack.us]
And then, most like what your article is about; with the camera stationary I could print up to about four letters with my laser pen: [img257.imageshack.us]

And I had to do all of this in a pretty dark room, otherwise the entire picture would be a total blur, as I couldn't adjust the exposure compensation (or whatever it is called) on my cheapo camera.

Oh sorry... forgot to link instead of embed. My bad... :/

Did this a while back with a friend... here's a combo shot taken over 3 photos... thought it came out pretty cool.

Note: There was only the two of us, so we were never in the same shot. So a lil Photoshop was used to combine photos, but the light is unedited.

@chareverie: Some of those long-exposure shots look like they were a lot of fun to make. Especially that one with orange loops by Toby Keller.

I bet you he just took an orange light in each hand, ran across the rocks and just windmilled it.

@Hadouken: Very well done!

@Hadouken: That's great!

I've tried light painting, and there is a lot of room for creative work as evident from the tutorial posted. While using a flash-light and sock (for diffusing the light), I was able to create patterns and such. I even painted myself with the flash light and a 30s exposure. Here is a flickr link of my attempts at light painting (drawing): [www.flickr.com]

As for a serious project in this technique, I intend to create a series of portraits. I think there are tremendous possibilities, and present relative difficulty in creating a piece of art that is both fun and interesting.

I've been playing around with it recently. Pretty tricky to coordinate. you can see my set here: [www.flickr.com]
