Sanderling – Blind Pass; Captiva, Florida: This is another shot taken with the Frisbee/ball head combination at Blind Pass. I shot this image a few minutes after shooting the turnstone in the previous post. I do love the low shooting angle that the Frisbee/ball head combination provides. The image was shot at a wide aperture of f4, The wide aperture provides a shallow depth of field isolating the Sanderling against other birds in the flock. Shallow depth of field, or selected focus is an essential composition technique when using long lenses.
