Every aspiring wildlife photographer’s dream is to acquire a big telephoto. For me, the dream came true when I was able to get my hands on Canon’s 300 mm f2.8 IS L lens, one of the sharpest lenses ever made, and a perfect reach, size, and weight for the varied wildlife photo opportunities that abound here in Costa Rica. But upon discovering a creature to photograph, it’s easy to forget the other lenses in your bag. Luckily I didn’t forget my other lenses a couple of weeks ago at the Selva Verde Lodge in the northern lowlands of Costa Rica.
While at Selva Verde for a conference, I snuck out early one morning to see what wildlife might be around the lodge grounds. Not 5 minutes later, the lodge manager told me that there was a caiman in the creek up by the reception desk. I approached the caiman as I normally do when out for a hike — armed with my tripod-mounted 300 mm lens and 550 EX flash with Better Beamer on my 20D camera body. Indeed, the caiman was there, and he was big, about 6-7 feet long, which is close to the reported limit for these tropical cousins of the alligator. I started at once to compose some portrait images with my 300 mm lens, and these turned out nice, particularly with a bit of fill flash to open up some shadows around the eye.

But the portrait didn’t really capture the mood of the scene that I was viewing — a caiman floating in a blackwater stream with dappled sunlight coming through the forest canopy. Luckily I had thrown a 28-70 mm lens in my waist pack, and I quickly mounted this on my camera body and moved closer to work handheld because it would have been very difficult to set up a tripod without disturbing the caiman from this closer distance. With this wider angle lens, I began to get images that looked like they could have been taken along the farthest reaches of some unnamed Amazon tributary stream. In reality I was about 100 feet from the reception desk at the lodge! I used a polarizer and varied the rotation to provide for different degrees of reflection. I also raised my ISO to 400 to get faster shutter speeds since I was handholding. I composed the frame to take advantage of the dappled sunlight on the water, which draws the viewer’s eye through the frame to the caiman.

These last three photos show the caiman in its habitat and because of the light and the reflections on the water, they have a mysterious look that will make impressive images when printed big. The lessons from my 10 minutes with the caiman at Selva Verde are two. First, if you have a big lens, use it by all means. These lenses are awesome! But don’t neglect the smaller, lighter, and cheaper lenses in your bag. Second, if you don’t have a big lens, don’t neglect wildlife photography. Sometimes a photo of a creature in its habitat is more impressive than a tight closeup. Wildlife habitat photos, however, require a good eye for composition so you don’t end up with a small subject lost in a chaotic environment. Look for leading lines and diagonals to strengthen your composition and make the subject stand out.
