"The Mean Stuf" is the tag line for a security product called Razor Ribbon Helical
. Often used with old fashion concertina wire, the tight loops of razor wire make for a nasty barrier. However, I have often noticed how the sun plays off the shiny surfaces, changing with each helical turn. So late this afternoon I took the opportunity to make this picture. Canon 7D, 1/800 sec @ f/8.0, ISO 200, 55mm focal length.
