All of these were shot with a Canon 135mm f/2 L series lens aperture set at 3.5-4 , some with indirect flash, the others available light only. All shot on a tripod, outside with heavily diffused light with temps in the 40s.
I was sitting on the back porch in my Captain Kirk swivel chair and this is what I saw. Canon 40D with my EF 135mm f/4 L. Hand held. The bottom shot was at f/2.5 as to blur the background. The dog is Cooper, our little Pomeranian.
