Bonnie and I were playing along one of our favroite stretches of the Blue Ridge Parkway last weekend when we found ourselves looking out over the Cradle of Forestry from Pounding Mill Overlook. One of the wonders of working in July in the Southern Appalachians is the significant potential for wonderful atmospheric conditions as afternoon showers come and go, leaving in their wake valleys filled with moving clouds of white, hugging the low ridges as they wander.

A focal length of 112mm, still fairly short telephoto-land, gave me the angle-of-view I wanted, which isolated the cloud cluster within the wider valley, and also a bit of magnification. An aperture of f/16 provided depth-of-field and along with a shutter speed of 1/10th second at ISO 100 gave me an overall very slightly-lighter-than-medium exposure.

How often are we fascinated, as was Joni Mitchell, by the illusory amazement of traveling forms of water vapor, clouds which, when we see them, may never be seen in that same way again?
