The afternoon sun cast an interesting light on this old and rusty bicycle sprocket. Canon PowerShot SD1100, 1/50 sec @ f/2.8, ISO 200, 40mm equivalent focal length in macro mode. Image converted to black & while using Silver Efex Pro in Photoshop Elements 6. Small point and shot cameras do a remarkably fine job with macro photos. The macro mode on the camera just tells the auto focus to look for the focus point much closer than in normal mode. Give yours a try, get close and I think you will be surprised by the results.
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.
