This is why I carry my camera on the front seat of my vehicle! I glimpsed the turkey vulture as I drove by, jammed on the breaks, pulled over, grabbed my camera and slowly headed back on foot. The bird was backlit and I knew I wouldn't have time to circle round him, so I just shot into the light, metering off the trees behind the bird. In Lightroom I lowered the highlights in the trees and raised the shadows and exposure in the bird. He's still an ugly bird, but I found him in a beautiful setting!
