arctangent's Photos : Popular Photos : Second molt. This is the time of year when male mallards molt back from their brief summer eclipse plumage, which is nearly indistinguishable from that of the female, into their beautiful and easily recognizable breeding plumage. The male of this pair seems to have barely begun this process, but the feathers in the water witness that it has begun. Huron River, Gallup Park, Ann Arbor, Michigan. September 19, 2008

arctangent > Ephemeral and exquisite.

Bloodroot is my favorite spring wildflower. The light and shadows here are less than ideal with some of the outer petals blown out, but this shot shows the intrinsic sparkle of the petals better than my other shots, and gives a sense of the overall delicacy of the blossoms.

Can you tell I haven't been outside the house for the past few frigid days?

arctangent > Frost macro #6 - feathers of frost on a window

I took this, and it still doesn't look real, even to me. Please look at it in one of the larger sizes, and enjoy the detail, and the way the sky has reflected from certain facets in the ice crystals.

Unfortunately, I took this handheld, manual focus, and didn't have the lense parallel to the window, so the focus falls off toward the upper left of the picture. Nothing's perfect.

$arctangent > Fiber optics. I wonder if anyone has ever measured the refractive index of milkweed floss, or its reflectivity. It provides endless pleasure and fascination to millions of people each autumn, to see the light shine through it and bounce from it.$
