I should have noted this when I submitted the image, but I was looking for a good exposure, rather than any artful meaning - My bad, but I'll remember to add caveats in the future.
The vast majority of my work lately has been ending up as black and white images. With that in mind I've been putting more time into getting a good initial exposure, rather than trying to manipulate the image later in Lightroom. For the submitted picture I selected aperture priority, set the exposure for the mid-tones, shot with recommended shutter speed, then another @ + .3 f/stop, and one more @ + .7 f/stop. In Lightroom I adjusted the image to the point that the details in the shadowed areas began to emerge. The sky was overcast so I left the highlights as shot.
