We had some extremely foggy weather today so I decided to visit the park to take a few shots. It was amazing watching these birds being feed by the person you see in the photograph. Hundreds of them would glide, swoop and dive frantically - disappearing and reappearing in and out of the fog - every time she cast the bread out of her hand into the water.
Taken at 24mm, shutter speed 1/400, aperture 4.0 and ISO-200. Some curves and level adjustments in Photoshop.
