This nasty little sticker ball is surrounding those chestnuts that they'll sing about roasting on an open fire in a few months. Do people actually roast chestnuts? Anyway, my next door neighbor has a large old American Chestnut tree in her back yard. The tennis ball sized stickers drop to the ground and open into four wedges releasing the nuts inside. The thorns are very sharp and quite effective at protecting the nuts. Canon 40D, 1/250 sec @ f/11.0, ISO 400, 50mm macro lens with off camera flash at 1/64th power.
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.
