I'm new to UHH and this is my first photo posting since joining. I photographed this American Bald Eagle with a Nikon D500 and a Nikkor 200-500mm F/5.6 lens and a Nikon 1.4 II Converter. ISO 640 Exp. 1/2000 sec. F/8 Focal Length 280mm handheld in a vehicle. When a vehicle is running whether a car or a big truck, they vibrate and it will affect the photographs. I started using my tripod with a wireless remote to compare to my handheld photographs. And to give my arms a break from the weight. What a difference! Trying to track birds in flight with a tripod is something to get used to. With time and patience i hope to master it. Enjoy!
