We looked to make an image which illuminates the other worldly beauty that we've both found going to festivals over the last 20 years. We believe the image captures a vision of transcendence and view of alien inner worlds. The camera was a Canon XSI, the flash was a Speedlight 430EX II with a diffuser and the lens was a Canon EFS. The laser was a 1 Watt RGB laser. Elana did her own hair and makeup. The camera settings were 800 ISO, 4.0 f-stop, and 2"5 exposure. - Ben Heise

That's me in the sunglasses - don't want laser in my eyes. Tripod-mounted Canon 60D, f/5.6, ISO 200, two 13 second exposures. One with horizontal laserpointer lines, the other with the lines at an angle. The laser pointer was green, by the way. Brought each image into Paint.NET, and adjusted the hue to blue and yellow. Superimposed the images, turned the blending mode for the top layer to additive, expanded the canvas and made a slight adjustment to the upper layer, moving it a bit to better overlay the bottom layer. - Brian Hall

I call this photo daylight savings because it cost me an hour of sleep. I was having trouble sleeping so I was up at 3 am playing with a laser level and trying to capture a photo for this challenge. The next morning I couldn't wait to look at the results but they looked much better to me at 4 am than at 9 am. The insomnia did give me the idea for using the glass ball from the top of my bedroom dresser. I grabbed the laser level and a green laser pointer, set my camera on tripod and framed the final shot on my bed. Canon 7D with EF24-105 lens and f/9.0 for 30sec at ISO 400. - Brian Jones

I decided to go the quantum mechanics route with this challenge. I got my red (650nm), green (532nm), and blue (405nm) lasers and used double slit gates to split the beams into interference patterns. At first I was projecting the beams onto my wall but the blue laser wasn't being adequately reflected. I thought all was lost until I noticed that my blue shirt did a splendid job... so I used that instead. I really like how the interference patterns demonstrate the different laser wavelengths. Post processing was minimalist and included some minor color balancing and cropping. My 40D died a few years back so I shot this with a Casio Exilim EX-FC100 at ISO 100, f=6.4, 32mm lens. - Brian Nietfeld

I had some prisms from a old CD player and a green laser from my target pistol so i figured I would try playing around with some cool ways to light the prism up. Looked cool sitting on my Galaxy S II phone glass. Nikon D3100, ISO100, f/5.6, 1/3sec, Kit lens. - Bryan Donahue

Other than photography, I would have to say my other passion lies in music. So when I am able to combine the two together, I am probably one of the happiest people you will meet - and that is exactly what this weeks challenge let me do! In the picture provided, I went to see a few local DJ's perform with an amazing laser light show going on behind them while they played. My goal was to capture the intensity of the lasers used during the show, expressing the different energy level of each song being played. Overall the show was amazing, and I haven't had so much fun taking pictures of lasers before until this challenge. This photo was shot with a Nikon D7000. Exposure time was 1/13 of a second, F-stop was f/4.2 and the ISO was set to 1600. - Bryndan Bedel

Party Time! I always used to enjoy watching people create their own light shows with the disco balls at the clubs; I decided to do the same for this challenge. I used a 5mW Blue/Violet 405nm laser and just went at it (with eye protection, I like my retinas the way they are!). I kept trying different shots with other laser set-ups but always kept coming back to the disco ball. The scene wouldn't have been complete without the handy help of my friends fog machine, especially since the laser I used isn't seen well by the naked eye. I guess I should have had a few friends over and had a real party! Camera - Nikon D90 on a Velbon Tripod with Remote Shutter Release. Lens - 70.0-300.0 mm f/4.5-5.6, Shutter speed: 30 secs, Aperture: f 8, Iso: 200 p - Chris Edwards

I started with a photograph of a petroglyph from dinosaur national monument, turned the bitmap into a line drawing, and used inkscape to vectorize the line drawing. i converted the vector into ilda and projected the image on sandstone via my homebuilt rgb laser projector. the blue and green background is from a second home built laser system. this system projects lasers through rotating shower glass creating a traditional planetarium style lumia effect onto a black backdrop. the red and the orange light on the rocks was achieved by gelled strobes triggered by radio. all the laser equipment in this shot is home built. i have included some photographs of the systems i used. this is not photoshop. there is no compositing. These photos were shot with a nikon d7000 iso 400 with an exposure time of 2/5th's of second and an f-stop of 32. - Christopher Short

Sadly it was too windy to use our fog machine outside for my original idea. My friends an I decided our best course of action would be to "hot box" the garage with the fog machine and drink some beers while discussing alternatives. Very quickly we all all had to use the men's room and one of my friends thought it would be funny to pretend the laser beam was filling up his beer bottle in the manner you see here. Likely much due to the inebriation of our collective minds, we also found this to be absolutely hilarious and thought it might make a good picture. We had to experiment quite a bit to get the exposure right since the blue/purple laser isn't nearly as powerful as the red or green was. We finally settled on a super long exposure with the blue laser on the whole time and the green and red lit up for just the last second of the shot. Canon T3i, 48 second exposure, F4, 800 ISO - Colin McLellan

Turns out, that a laser disc will cause a laser to refract in pretty interesting patterns when shining one upon it. We used a fog machine to cause the beams to be more visible, but otherwise the photo is mostly unprocessed. Canon Rebel T3i w/EF-S 18-200mm f/3.5-5.6 IS ISO 800 f/4 1/4 second exposure - Colin Robertson

For inspiration, I dug up my green laser and walked around my house pointing it at anything reflective or glass. Finding this glass figurine (originally from Amboise, France), I used the laser to light him up. The longer shutter speed (8 seconds for example) lit it too evenly, so the faster shutter with tighter aperture worked better. You can see the laser on the ground below the base of the figure! Canon T2i, 3"2, f/20, ISO 1600, kit lens (18-55) @ 24mm. -David Runde

I set up the minifigs on a black T-shirt and the 30D on a tripod. I drew circles around them with a green laser and shot images with a remote trigger connected to the camera, experimenting with different shutter speeds. Shot with Canon EOS 30D, 17-85mm IS Lens, ISO 200. - Debbie Negari

After realizing that I have a 90-yr-old person pulse, I discarded all of my ideas for "precise" light painting. For this specific photo, my main challenges were 1) Modifying the camera settings so the background was dark enough and get his face lit by the laser (but not overexposed), 2) Having enough time to "paint" the full surface of the IKEA pencil that acted as a light saber (with my shaky 90-yr-old person pulse), 3) Shooting the laser at an angle that did NOT show in my background and 4) Painting the damn thing over and over and over until I got it just right. Canon T2i, 100 mm lens, f/5, ISO 100, 10 seconds. I also spent some time in Photoshop rounding up the top of the pencil (so it looked like the real deal). - Diego Jimenez

I pointed a red laser at the LED and took a series of shots with the remote trigger at varying shutter speeds. Lasers make for good spotlights, and here it makes the LED look like it's glowing. Lego Minifig with LED, shot with a Canon 30D, 17-85mm IS lens at 85mm on a tripod, ISO 200, with remote trigger. - Ed Negari

This is my first entry in the weekly photo challenge, I was looking for a subject to use with my 200 mW red and blue lasers. I first tried a simple glass with red light, and I finally came up with this idea. Luckily, I was alone in the house, I just hope my mother don't see this shot, she would never forgive me for putting ice and pointing lasers in her flower pot ! The shot was taken in Québec, Canada, at f/25, 30 sec. and ISO0-400, with a Nikon D5100 at 19 mm. - François-Xavier Ratté

As suggested in the challenge I wanted the laser to be the subject. I like that the beams stands out against the world's tallest building - the Lego Burj Khalifa and assorted nails and pens used for the skyline. The laser is from a Christmas themed DJ'ing box that I got on discount before ripping out all the spinny Santa Claus etchings. This left a simple green and red laser beam. No photoshopping beyond desaturating the RAW file and adding a small highlight to the top of the tower. Shot on a table against a blue background with a red filtered light behind the skyline. The curve of the beam was achieved by bouncing the beam off the edge of a metal saw. Canon Eos1000D ISO 100, 10-24mm wide angle lens. I spent the whole time terrified that I'd direct the beam into the sensor. No more scary challenges please. - James Slade

I wanted to "split" the beam of the laser into multiple beams. After trying a few things lying around the house I finally stumbled on my wife's wedding ring! I pointed the laser right at it and really liked the look of all the facets of the diamond "splitting" the laser beam. In photoshop I did some cropping and turned the laser from red to blue. Canon T2i w/ kit lens f5.6 1/2s iso 200. - Jared Grayden
