I wanted to take this photo in one long exposure but, unfortunately, I snapped my wired trigger off in the port a couple days ago, so I was stuck with a 30 second limitation. I got past this by taking 5 separate shots and stacking them in Photoshop (one of my stepson posing one each side, one of each "fireball" and one of the explosion in the middle). Surprisingly, I only ended up with a couple throwaway shots. Everything went pretty smoothly. My stepson was ultra-impressed with the final image and felt like a superhero. Shot with a Nikon D7000. Tokina 11-16mm UWA lens. Five 30-second shots at 100 ISO, F18 - Jason Hilt

Beams of light broke the foggy darkness. A figure emerged, his silhouette breaking the light. Who was he? A time traveler? A visitor from another world? No...it was just me standing in front of a laser projector, trying not to violently shiver and mess up the shot. This one is actually pretty basic, but it took numerous attempts to get the right angles and for me to hold still enough for the 30-second exposure to get the desired effect. A fog machine helped to illuminate the laser beams and add some ambiance to the scene. Photoshop was used to remove a stray LED in the background and up the brightness/contrast.

I saw this Shooting competition on the day that we took delivery of our new RGB laser at work, so naturally I took it as a sign to experiment with some shots! It was shot on a Sony Alpha 350 18-70mm lens with a 3.2 second exposure with me stood in the middle of a darkened stage. ISO 200 f/13 - Jim Cooke

The Lasers are 3 X-Laser X-PODs in red, green, and blue, pouring into the viewfinder of a DSLR that has already been fried by lasers (this is why you don't point lasers right at your camera) Shot with a Nikon D2Hs, Tokina 100mm 2.8 macro lens at 1/60 and wide open @ ISO 200. - Joey D'Anna

Cat wrangling. Like nailing jello to a tree. My husband and I had an easy one - armed with a laser pointer, flashlight and tripod - it would be so easy to catch a shot of the cat chasing the laser. We have TWO cats. As it turns out, two lazy, willful cats. It was impossible to get them to do the thing they ALWAYS do when it comes to the red dot. Oy. So while we were playing with other ideas in the vaporizer...little miss nosy finally decided to check out what we were up to. f2.8, 2 sec, ISO-80 - Karen Tarlow

The goal for this picture was to make it look like the laser was lighting the match. I put the match in a clamp, and taped a laser pointer to a stand, aiming it directly at the match head. I set the a 10 second timer, and in that time, lit a separate match, and put my hand in front of the lens. Once the exposure started, I kept my hand in front of the lens, and lit the match in the picture, quickly removing my hand at the moment of ignition, so I could get the unstable combustion look in the picture. If I didn't put my hand in front of the lens in the beginning, the match I lit this match with would have gotten into the picture. After the lit match started a stable burn, I put my hand in front of the lens again, and blew out the match. Then I removed my hand in front of the lens, and my girlfriend dusted a healthy amount of baby powder from above to make the laser beam visible. I had to blow out the match first because corn starch baby powder is flammable when mixed with air. I'm very glad I knew that. It took us a few tries to coordinate this, but it ended up working pretty well. Canon T2i 18-55mm lens @ 55mm. ISO 100, f/9, 15 second exposure. - Matt Gurbarg

When I found out about this weeks challenge I'd already decided that this would be the first week I'd participate, regardless of what you might throw at me. When I found out it was a laser theme I was excited to go to laser tag and get some intergalactic warfare shots. But I've learned cameras of any kind are strictly prohibited at laser tag. I have also learned this prohibition is enforced by several large and aggressive laser tag staff. There was the possibility of a club but I hate clubs, especially ones with epileptic lasers. There were no concerts in this sleepy city either. Lasers. Fuck me. I bought a laser pointer and a barbie doll. I decided to bring the club to me. I sat barbie on my computer keyboard and put a screen saver on. I used a tripod and while the 13 second exposure was going I drew onto barbie with the laser pointer. This was the first of several attempts. It's my favourite because I think she looks a little bit scared.

My future father-in-law and I took many shots my fiancée's diamond ring illuminated with a laser pen and LED flashlight. We wanted a good white semi-reflective surface as a background to emphasize the laser points, so we ended up using our first piece of wedding china, incidentally theming the photo. He had the sense to wear sunglasses, but I'm still seeing spots. The biggest challenge was avoiding artifacting and overexposure from the reflected laser points, so we narrowed the aperture and used spot metering on the brightest spots to get them defined. We used a Nikon D300 and a 60mm macro lens at ISO 200, f/16, and a shutter speed of 1/50. - Nicholas Spencer

I had the picture painted well in my mind - a smaller fish about to be eaten by a larger fish, unaware. But drawing it was the hard part. If I went to close to the ground to "draw" with the laser then I would block and ruin the photo, if I aimed from too far then the lines became too uneven because of the shakiness of my hand. Finally after about 50 images and after spending an hour trying to get a decent image, this was the result. Oh and by the way this image was taken at night, streetlights are causing the glow in the sky not the sun. Taken with my sony nex c3 with f/3.5, ISO 200 and a shutter speed of 30 sec at 18 mm. - Paramjot Jhun

OK, I don't own a laser pointer. But I love this challenge! I had a cool Star Wars figure + my favorite matchbox car = Alien invasion! I've been playing with my Panasonic 45mm macro lens (micro four-thirds) that I really like - it gives great depth of field. Camera is Olympus E-P1. This was taken at f/7.1, 1/30 sec, ISO 800, on a tripod (it was pretty shady). I tried to think of ways to use a laser pointer to hit the eye directly, but then the laser shot would be firing off the end of the photograph... boring. The alien is shooting at the car! My "laser" was made with the line tool and a couple blur layers in Photoshop - hope that counts! - Peter Welch

The photo is a self portrait that was taken at the laser show using a timer. I did this myself by setting the camera on a 10 second timer running in front knocking people out of the way throwing my hands in the air. I did this repeatedly until I got a desired shot. People kept looking at me like a mad man running around with my hand in the air. I got to admit, leaving the camera without supervision even for 10 seconds was a bit nerve breaking.

This shot was taken at the TECHNICOLOR 2 dance and laser light show event in Houston, TX. My friend and I found out about the event just after reading the latest Giz shooting challenge, so we figured we had to go. Managed to get permission from the coordinators to bring DSLRs in, and the fun was ready to be had. Neither of us had ever shot an event like this before, so it took some learning as we went along, but we ended up with a bunch of really cool shots. Shot on a Nikon D7000 at 1/15 and ISO 800. Lens was a Nikkor 35mm at f/1.8. Originally tried for longer shots, but found that I liked the crisper look of the lasers in the short shots better, so I spent all night shooting the fastest lens in my bag, the little 35mm. The bartenders at the back of the event were cool, and let me set up my tripod on a platform behind the bar, so I was able to get some cool shots of the laser effects without having the crowd blocking my view. - Scott Wallace

Rather that do light-painting or use the beam itself as the subject, I decided to do something different and use the laser as illumination. I thought something beautiful and organic (like this fake plastic lily) would contrast well with the harsh, technological glow of a 5 milliwatt, 532 nanometer green laser. Is this the way those 3D laser scanning machines see the world? Shot on a Canon Digital Rebel XTi using a Canon 70-300mm f/4-5.6 IS USM lens at 80mm, f/25, 20s at ISO 100. I set up focus and composition under normal lighting, then blacked-out the room so that the only light source would be the hand-held laser. Then it was full-on Manual Exposure, adjusting aperture and shutter speed until I got something I liked. I used one hand to operate the shutter release cable while the other hand made PEW PEW with the laser. - Shaun Wrightson

I got the general idea for this photo from the Flickr group that was linked to by the original contest post. There was one with a laser going through an apple, so I decided to try that with an egg. My dad kept telling me to light it on fire to make it more interesting, so I gave in. This shot is actually three mixed together. One is the laser beam, one is the egg on fire, and the final is the red dot on the egg. Other than layering the three different pictures, basic editing was used. Nikon D3000 – ISO 400 – f/5.6 - Spencer Lund

I was thinking along the lines of abstract/sci-fi. Conveniently, I had a fiber optic stand laying around and thought using it would create a cool lighting effect. I laid it horizontally on a towel hanger in a dark bathroom, and used a red pointer laser to flash against the wall; the focus being on the laser. Nikon D40 with an ISO of 800, 90mm, f4.8 1/30s. - Stacy Repin

When the contest was announced I immediately thought crystals. Using my small Swarovski crystal collection I thought I would try to showcase their trademark swan with a green laser pointer. A host of mirrors, glass, and figurines were used to come up with this, the last and best shot of the night. Through all this my dog was going insane chasing the reflected/refracted laser spots across the floor. Shot with a Canon Rebel T3, stock lens, f22, iso 400, for 3 seconds. - Zac Wallace
