There was a small flock of royal terns on the Captiva, Florida beach just north of Blind Pass and Sanibel Island. It would have been easy to stand and capture distant photos of the flock resting in the sand, but I was looking for something better. By lying down in the sand and moving forward slowly, the beautiful birds allowed me to get quite close without showing any signs of stress. So close that I had to zoom out somewhat to get the framing I selected for the bird in this photo.
That the 100-400 L II focuses so closely is a big benefit when the subject is small and you want to fill the frame with it or a portion of it. The close focusing is also useful in situations such as this one – when I got too close. As I said, there was a flock of birds and I was photographing various birds as their positions and behaviors warranted my attention.
A low shooting position often has the benefit of a clean background (the sky in this case) and provides a nice angle on most small birds and animals located on the ground. To make shooting while lying flat in the sand easier, I utilized a NatureScapes Skimmer Ground Pod II. To help darken the sky in the background, I used a circular polarizer filter.
Early and late in the day sunlight often provides the best lighting for bird photography, but nice images can be made at other times of the day. This royal tern photo was taken at 11:44 AM. At this time of the day, the sun is near its highest point, making shadows harsh and the color temperature of the light cool. By carefully timing the shutter release, I was able to catch bird positions that minimized shadows (especially on its head) and that included a catchlight in the eye. Sunlight reflecting on sand also helps minimize shadows (though not as well as the snow that was on the ground at home on that date does).
With a white bird in full sunlight and under a cloudless sky, the exposure decision was easy. Lock in manual mode settings that included a shutter speed fast enough to stop any movement present (there was lots of action happening), an aperture that provided adequate depth of field and an ISO setting that caused the brightest areas of the photo to be *just* below blown (pure white) in brightness.
The 7D Mark II and 100-400 L II performed extremely well on this trip. The alert among you will notice that the reported full size pixel dimensions for this image are larger than those native from the 7D Mark II. I framed this bird tight to the top of the frame and used Photoshop's content aware fill to extend the canvas, creating more sky in the final image. This tactic created a modestly higher resolution image overall. Another option for increasing resolution would have been to capture a similarly-focused second frame with more upward angle, taking in much more sky for later stitching to the bird image.
I spent hours focusing on these birds and will try to share some additional images when I get time.
