Since I wanted to place the sun behind him I had to use flash in order to fill in some shadows. I had the camera set to aperture-priority and the flash to rear-sync to expose the background better, otherwise I was afraid the sky might come out too dark. Memory fails me if I even bothered to look through the viewfinder to frame the shot, but I don't think I did. (Looking through the viewfinder in the sun's direction is a dangerous thing to do.) I suppose it would've been nice if the leash wasn't in the picture, but I'm not about to ask my friend to let Bootsy off-leash. I added a vignette using Lightroom.
Two things are visible that I didn't notice at the time I took the picture: a jet contrail, and a nose droplet.
(Shot with the Nikon D300 using the 18-200mm zoom and the SB-800 flash; lens set at 18mm; aperture-priority with aperture set to f/3.5; camera chose shutter speed of 1/1000 second at ISO 200; normal JPG.)
