This photo looks like a shot of a lake but in fact it's a very low spot in a field that in a few weeks will be seeded with wheat...or something along those lines. The ice pattern in the foreground looks like a giant foot print I think.
Canon 5DII with Canon 24mm TSE lens; f16, 1/30 sec. ISO 100. Singh Ray LB Colour Combo Polarizer and Singh Ray 2 stop hard edge graduated filter over the portion of the photo. All supported on Gitzo Explorer tripod fitted with Really Right Stuff BH-55 ball head and matching L bracket.
