Wannabe Green? The compact fluorescent lightbulb (CFL) is one way to help save the world. If each household in the U.S. swapped out one 60 watt traditional lightblub it would save enough electricity to power all the homes in Delaware and Rhode Island. In terms of oil not burned, or greenhouse gases not exhausted into the atmosphere, one bulb is equivalent to taking 1.3 million cars off the roads. Houses in the U.S. have 50 to 100 sockets, imagine if they all had the mighty CFL in them. Canon Rebel XTi, 1/250 sec @ f/20, ISO 100 with two off-camera strobes, one with a green gel. Thanks to Fast Company for the facts and figures and to Strobist.com for the lighting concept.
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.
