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.
From 365 Project The Air Force Memorial in glows against low hanging clouds and mist. Located on a promontory in Arlington, Virginia, overlooking the Pentagon and adjacent to Arlington Cemetery, the memorial's three 270 feet tall stainless arcs evoke the spirit of flight. Taken with a Canon 40D, 5.0s exposure at f/8.0, ISO 200, 28mm equivalent focal length, mounted on a tripod.
This is a reproduction on an early 20th Century "squirrel cage" carbon filament light bulb built by Thomas Edison. In today's modern reproductions the filaments are made of tungsten, which burns three times brighter than the original carbon filament versions. They are really getting popular in vintage bare blub fixtures. This one was hanging over my table at Tarrant's Cafe , 1 W. Broad Street in Richmond Virginia. Canon G15, 1/15 sec @ f/8.0, ISO 200, in macro mode.
