Got my Dragon Lasers fan diffraction gratings today, just in time for Christmas, so of course I had to take some new pictures! This is my first attempt at photos with the diffraction gratings and fog and I have to say it was the coolest photo session yet. It was surreal being in pitch black, surrounded by thick fog and these beams fanned out like this. It really felt like being in some sci-fi movie scene! Well, here are the photos, hope you all like them!

DL Spartan 50mW (107mW peak) 589nm:



100mW 532nm:



589nm and 532nm:



589nm horizontal and 532nm vertical:



589nm and 532nm flat fans:





589nm and 532nm behind the scene:



Finally, for Christmas, 30mW of 532nm and <5mW of 650nm:



UPDATED SECTION:

Lasers: 2.3W 445nm
100mW 532nm
50mW (107mW peak) 589nm

Neat! I really like how you managed to make your 650nm stand out agaisnt 532nm and 589nm :)

Hi everyone, just wanted to update my thread with some new photos and some other information. I wanted to briefly mention what equipment I am using and some other points about how I am taking these photos just in case someone sees this that is thinking about trying laser photography for themselves. First of all, I am by no means a pro at this, far from it, but I enjoy it and that is all that matters for a hobby right? :) Plus, if I can do it, anyone can. :D But I wanted to touch on some things I have learned during my experimentation with laser photography.

So, I am using a Chauvet DJ Hurricane 700 fog machine, a Canon EOS 30D DSLR camera, Canon EF 28-200mm f3.5-5.6 USM zoom lens, 2 Dragon Lasers diffraction gratings and tripod mountable clamps for my lasers. I use auto settings on the camera, manual focus and self-timer mode to take the photos in RAW format. Sometimes I use manual modes and experiment with different settings on the camera (ie. ISO setting, aperture value, shutter speed) too when I find something is working better than auto, just have to practice and try different things. Sometimes auto works great, other times not so much.

I use spring type clothespins to hold my diffraction gratings, so far this has been working well as I can set them at any angle and they are pretty stable on a flat surface. I take all my photos seen here in my basement because I have no ambient light to affect my photos and the fog stays around for a long time. I find you just need to have patience and experiment and see what works well. Take a lot of photos, see what works and what doesn't. After the photos are in the camera, I use Photoshop for processing the RAW files, save them to JPEG and then you see my end results here.

Also, side note on safety: These pictures I have taken now are my first attempt at diffracting my 2.3W 445nm and photographing it down range. This required the utmost in caution setting this up, using my safety glasses, making sure that all reflections are below eye level and moving very slowly because I don't know how much power would be in a diffracted reflection off the back of the grating but I did not want to find out what would happen if I got hit in the eye from that. Also when you are setting up shots like this with the camera down range, make sure no laser light enters your lens, I always make sure to slowly adjust my lasers from below the camera lens upward till they are in position. Then as I make absolutely certain no light is entering the camera I use my <5mW laser to adjust the focus of the camera to where I need it. The last thing you ever want is to be staring through your viewfinder and a Class 3B or 4 laser beam enters the lens of your camera giving it right to your eye. I must say I was on my guard every time I had my 445nm lasing while the photo was being taken. You get a lot of diffracted beams from the backside of the grating too so you must be very careful when diffracting your high-powered lasers. Even good safety goggles might not be enough to protect you from a direct diffracted hit, I don't ever want to find out.
