Hayward, California, United States
"This photo was taken at the Don Edwards wildlife sanctuary in Alameda County, CA. The pump house in center background releases water to regulate flow into the sanctuary. I also liked the serpentine flow of the stream."
"Photo taken with pinhole lens made from a Nikon body cap and 0.25 mm commercial pinhole disk taped to the inside of the body cap. The lens cost about $10 to make. The exposure was 2 seconds in bright daylight."
