My 17 year old brother, Jackson is an apprentice falconer. This is one of the silhouette shots I got of him with his Red Tailed Hawk, Gabriel. I slowed my shutter speed down to 1/30 in an effort to "see" Gabriel's wings move as he flew off of Jackson's arm. I used center weighted metering, knowing I would off center Jackson and the camera would meter for the sky (that is in the center)-making him a silhouette.
