When capturing photographs of eagles, research eagles behavior in advance, use a camera with powerful lenses, use binoculars to differentiate eagles from other birds when they are far away, and use a high shutter speed. It is prudent to ensure adequate lighting and set the camera to the ground level.
It is important to learn the behavior of the eagles, their habits and habitat to capture good shots. Eagles have a habit of relieving themselves before flying. A photographer can predict their movement and shoot a good flight photograph. When taking a close-up of an eagle becomes difficult, take a unique shot of the bird while in its habitat. Keep the ISO low to prevent digital noise from affecting the photographs.
Use the largest and fastest lenses and a tripod to capture great shots, as opposed to handheld cameras. Using a high shutter speed helps capture the action of the eagles in flight. A high shutter speed also helps capture the eagles wings. Due to its large size, an eagle flaps its wings about two times in a second. The lighting should be sufficient to capture clear photographs, and you should adjust focus toward a point where the light falls adequately at different times of the day to avoid blurred shots.
