A couple of days ago, before this heat wave descended upon us, I was out in the Echoing Hope Ranch garden hoeing between cowpea rows. The soil was moist and friable due to a morning sprinkler irrigation. A killdeer was maintaining a safe distance from me, probing the ground for provender while keeping an eye on me, as you never know what those erratic humans might do!
A glint of something in the soil caught my eye. It was a fragment of glass. For some reason glass fragments are common out in the garden; perhaps it once might have been a household dump site.
I picked up the arc-shaped piece of glass, noticed that it had a pleasing iridescence, and stuck it in my pants pocket.
It’s a hot afternoon here in Cochise County. While sorting laundry I came across the chunk of glass. I became curious; could I capture that thin film of iridescence in a photo? I set up my tripod and shot this photo with the camera set at 1/13th of a second exposure.
