The eagle was photographed at the Sacramento National Wildlife Refuge, California. The photo was taken with a Nikon D750 a Nikkor 80-400 mm VR lens at 400 mm. The exposure (hand-held while leaning out of a window of a parked car) was f/11 and 1/800 sec (ISO 800). The sky was bright blue and cloudless, so I transplanted some local clouds from an earlier photo made with a Nikon D7000 and a Nikkor 16-85 mm VR lens at 40 mm. That exposure was f/8 and 1/2000 sec.
