DPSSFD

From 2010 Blog
DPSSFD (diode pumped solid state frequency-doubled) or better known as a green laser pointer. This photo was inspired by my friend Jeff Carr and his blog post entitled "High Energy" from last week. I experimented with firing my green laser at the camera and capturing the image. Because a green laser is much more powerful than a red laser, I waved the laser at the lens at a sharp angle while firing the shutter multiple times. I didn't want the laser shooting straight at the camera's sensor because of the intensity of the light. I certainly wouldn't recommend this technique because the risk to eyes and camera. The circles of green result from the beam refracting off the many glass elements inside of the lens. Canon 40D, 1/60 sec @ f/2.8, ISO 800, 17-55mm zoom lens at 17mm.

Cool result. If you want to try this without risk to your own vision, the EOS utility allows for remote viewing and control via your computer.

Thanks Jeff. I used live view and looked at the camera's LCD rather than trying to use the view finder. I haven't messed around with tethered shooting much. Need to try that out.

Really interesting.

I love how this came out. Those streaky lines give this a lot of life.
